Grandfather is wrong don’t do it

1. The simplified form of the expression 2x^2 + 4y + 3x^2 - 2y + 3y is 5x^2 + 5y.

To simplify this expression, combine like terms by adding the coefficients of the same variables. In this case, there are two terms with the variable x^2 (2x^2 and 3x^2) and three terms with the variable y (4y, -2y, and 3y). When the coefficients are combined, you get 5x^2 for the x^2 terms and 5y for the y terms, resulting in the simplified form 5x^2 + 5y.

2. To simplify the expression 2(6x + 18), distribute the 2 to each term inside the parentheses.

2(6x + 18) = 2*6x + 2*18 = 12x + 36

So, the simplified form of the expression is 12x + 36.

3. To find the product of 4 and -5, simply multiply the two numbers together.

4 * -5 = -20

So, the product is -20.

4. The equation itself is not provided, so there is no way to determine which property is illustrated by the statement.

5. The property illustrated by the statement 3.2 + 4 = 4 + 3.2 is the Commutative Property of Addition. This property states that changing the order of addends does not change the sum.

6. To order the numbers from least to greatest, compare their values.

-2/3 < -0.2 < 0.8 < square root of two < square root of eleven

So, the correct order is negative two thirds, negative 0.2, 0.8, square root of two, square root of eleven.

7. To simplify the expression 2 - (-8), use the rule that subtracting a negative is the same as adding a positive.

2 - (-8) = 2 + 8 = 10

So, the number line 2 + (-8) = 10 can be used to simplify the expression.

8. The number square root of thirteen belongs to the subset of irrational numbers because it cannot be expressed as a fraction or a repeating or terminating decimal.

9. To simplify the expression 9x - 6/3, you can simplify the fractional part first by dividing 6 by 3.

9x - 6/3 = 9x - 2

So, the equivalent sum or difference is 9x - 2.

10. The algebraic expression for the word phrase "the product of 6 and n" is simply 6n.

11. The algebraic expression for the word phrase "the quotient of 5 and the difference of x and z" is 5/(x - z).

12. The algebraic expression for the word phrase "the quotient of y and 6" is y/6.

13. To find the difference between -3 and -4, subtract the second number from the first number.

-3 - (-4) = -3 + 4 = 1

So, the difference is 1.

14. The simplified form of the expression "square root of one over one hundred forty-four" is 1/12.

15. The property illustrated by the statement k(mp) = (km)p is the Associative Property of Multiplication. This property states that changing the grouping of factors does not change the product.

16. To evaluate the expression u/z + xy^2 for u = 20, x = 4, y = 7, and z = 10, substitute the values into the expression and perform the calculations.

u/z + xy^2 = 20/10 + 4*7^2 = 2 + 4*49 = 2 + 196 = 198

So, the value of the expression is 198.

17. To find the product of 6 and -3, simply multiply the two numbers together.

6 * -3 = -18

So, the product is -18.

18. To simplify the expression (2/3)^3, raise the numerator and denominator to the power of 3 separately.

(2/3)^3 = (2^3)/(3^3) = 8/27

So, the simplified form is 8/27.

19. The word phrase that represents the algebraic expression 3m is "3 times a number m."

20. The simplified form of the expression -(12x - 8y) is -12x + 8y.

When you distribute the negative sign to each term inside the parentheses, the positive and negative signs in front of the terms change. So, -12x - (-8y) becomes -12x + 8y.

21. To simplify the expression 12[62 ÷ (52 - 42) + 4], follow the order of operations (PEMDAS). First, simplify the expression inside the parentheses.

52 - 42 = 10

Next, divide 62 by 10.

62 ÷ 10 = 6.2

Then, add 6.2 and 4.

6.2 + 4 = 10.2

Finally, multiply 12 by 10.2.

12 * 10.2 = 122.4

So, the simplified form is 122.4.

22. To simplify the expression Start Fraction 4sg over -5g End Fraction, divide the numerator and denominator by the common factor of g.

Start Fraction 4sg over -5g End Fraction = -4s/5

So, the simplified form is -4s/5.

23. If a player ran a total of 78 yards and ran 7 and 5 yards on his last two runs, then the number of yards he ran before those last two runs is found by subtracting the yards of the last two runs from the total yards.

78 - 7 - 5 = 66

So, the player ran 66 yards before those last two runs.

24. To find the value of Start Fraction x over y End Fraction when x = -15 and y = -3, substitute these values into the expression.

Start Fraction -15 over -3 End Fraction = -15/-3 = 5

So, the value of Start Fraction x over y End Fraction is 5.

25. Reasonable answers for multiplying a positive number and a negative number can include -6, 3, and -2. These answers depend on the specific numbers being multiplied.

26. Reasonable answers for the product of two negative numbers and a positive number can include 20 and -15. These answers depend on the specific numbers being multiplied.

1,2,3 ok

#4 no idea -- no statement given
5-8 ok
#9 ok, but you should have written (9x-6)/3
10 ok
#11, ok but 5/(x-z)
#12 ok, but why not just say y/6 ?
13 ok
#14. √(1/144) = 1/12
√1/144 = 1/144
be specific on just what is under the √
#15 nope. B would be
k(mp) = k(pm)
or
k(mp) = (mp)k
#16. again, parentheses are important
u/z+xy squared, for u = 20, x = 4, y = 7, and z = 10
u/z + (xy)^2 = 20/10 + 28^2 = 786
(u/z + xy)^2 = (2+28)^2 = 900
Other arrangements are possible, but they do not end in integer answers
How did you get B?
17 - nope. D is 6-(-3)
18 ok, but what's with the "end fraction" stuff? 6/9 not clear enough?
19,20 ok
#21
12[62 ÷ (52 – 42) + 4]
12[62/10 + 4]
12[10.2]
122.4
You must have a typo
#22. nope
#23. Nope - subtract the total yards already run: 78-(7+5) = 66
#24 A
25,26 ok
