a. Substitute (x + 2) from the second eq., simplify and solve for x. Then solve for y. The other two equations are done the same way. a. x+2 = x^2 x^2 - x - 2 = 0 (x - 2)(x + 1) = 0 can you finish it?

WOW! This looks like algebra, not 6th grade.

In your first question, do you know how to simplify an expression - that is remove parentheses? Question #2 parallel lones have the same slope I don't understand question #3 Question #4 perpendicular lines have slopes that are negative reciprocal s of each other.

If no height is given for the triangle, you cannot find the area. Does the triangle share a side with the rectangle? Could it be that the height of the triangle is one of the sides of the rectangle? Your area for the rectangle is correct.

problem 1. let x = first number 8x = second number x - 3 = third number x + (8x) + (x-3) = 207 simply the equation and solve for x problem 2 is done the same way as the first one

That is not the answer. There is no exponent in that equation.

Ok. Also -1 and - 19. The answer then is: -19, -1, 1, 19 Second question List all pairs of numbers that multiply to get -8.

algebra 1 help
What are the factors of 19? Your answer to the first question is not correct I'll talk about the second question after you get the first one correct.

algebra 1 help
In question 2, you are looking for all pairs of numbers greater than zero whose product is 8.

The first thing to notice in the first question is that 19 is a prime number. If you can list ALL factors of -19, then you have all values of k using integers.

You factored the expression 2x^2 - 7x - 15 and got (x - 4)(x + 2) If you multiply those together, you do not get the original expression. Your answer is not correct. the factors that have 3 and 5 in them are the correct answer.

(2x + 3)(x - 5)

your answer to 2x^2 -7x - 15 is not correct because if you multiply your factors, you get x^2 - 2x - 8
