Slope is easy you can look that up and the y- intercept is the point of the y axis
Answer:
(a) 10x^2−x−21
Step-by-step explanation:
The area of a rectangle is given by the formula ...
A = LW . . . . . where L is the length, and W is the width
__
The area of the given rectangle will be ...
A = (2x -3)(5x +7)
This product is simplified using the distributive property to eliminate parentheses. Then like terms are combined.
A = 2x(5x +7) -3(5x +7)
= (2x)(5x) +(2x)(7) -3(5x) -3(7)
= 10x^2 +14x -15x -21
A = 10x^2 -x -21
The expression 10x^2 -x -21 represents the area of the rectangle in square inches.
Answer is: 1/24 So first you need to convert and remove the parentheses and that will get you to -11/6+1 7/8 and then you convert the expression and you get -11/6+15/8 then you solve and get 1/24
Answer:
The error made by the student was that they didn't distribute the 7 first, they just added -2 and 7. The correct way would be to distribute first:
-2+7(x+8)
-2+7x+56
54+7x

Answer:
<h3>5 1/10 ÷ 6 2/5 = 51/64</h3>
Step-by-step explanation:
5 1/10 = 51/10
6 2/5 = 32/5
5/10 ÷ 32/5 = 5/10*5/32= 255/320=51/64
