Expand 7/10(5d+6)
Responses
5d + 21/5
35d + 6
35d + 42
7/2d + 21/5
To expand 7/10(5d + 6), we distribute 7/10 across the terms inside the parentheses:
7/10 * 5d + 7/10 * 6
This simplifies to:
35/10d + 42/10
35/10 can be simplified to 7/2, so the final expansion is:
7/2d + 21/5

To expand the expression 7/10(5d + 6), we need to distribute the 7/10 across the terms inside the parentheses.
First, distribute the 7/10 to the term 5d:
(7/10) * 5d = (7 * 5d) / 10 = 35d / 10
Similarly, distribute the 7/10 to the term 6:
(7/10) * 6 = (7 * 6) / 10 = 42 / 10
Now, we have two terms: 35d / 10 and 42 / 10.
To simplify the fractions, we can divide both numerator and denominator by their greatest common divisor which is 5:
35d / 10 = (35/5)(d/2) = 7d / 2
42 / 10 = (42/2)(1/10) = 21 / 5
Therefore, the final expansion is:
7/2d + 21/5

Apologies for the confusion. Actually, I made a mistake in the calculation. Let's redo the process correctly.
To expand 7/10(5d + 6), we need to distribute the 7/10 across the terms inside the parentheses.
First, distribute the 7/10 to the term 5d:
(7/10) * 5d = (7 * 5d) / 10 = 35d / 10
Similarly, distribute the 7/10 to the term 6:
(7/10) * 6 = (7 * 6) / 10 = 42 / 10
Now, we have two terms: 35d / 10 and 42 / 10.
To simplify the fractions, we can divide both numerator and denominator by their greatest common divisor which is 7:
35d / 10 = (35/7)(d/10) = 5d / 2
42 / 10 = (42/7)(1/10) = 6 / 5
Therefore, the corrected final expansion is:
5/2d + 6/5
Factor 9z + 18 using the GCF.
To factor 9z + 18 using the greatest common factor (GCF), we need to find the largest number that divides evenly into both 9z and 18.
The GCF of 9 and 18 is 9. Additionally, both terms have a common factor of z, as z is included in 9z. So the GCF of z, 9z, and 18 is z.
So, using the GCF of 9 and 18, we can factor out 9 from both terms, and using the GCF of z, we can factor out z from both terms.
9z + 18 = 9(z + 2)
Therefore, the factored form of 9z + 18 using the GCF is 9(z + 2).
Factor 16d − 12 using the GCF.
To factor 16d - 12 using the greatest common factor (GCF), we need to find the largest number that divides evenly into both 16d and 12.
The GCF of 16 and 12 is 4. Additionally, both terms have a common factor of d, as d is included in 16d. So the GCF of d, 16d, and 12 is d.
So, using the GCF of 16 and 12, we can factor out 4 from both terms, and using the GCF of d, we can factor out d from both terms.
16d - 12 = 4(4d - 3)
Therefore, the factored form of 16d - 12 using the GCF is 4(4d - 3).
