These are the correct ratios trust me I've done them a thousand times 15: 7 and 15to7
I think you meant to type in "at the point x = 2"
y = -3x²
y' = -6x
y'(2) = -6(2)
= - 12
Answer: slope is -12
The number is x
4x+40=100-x
add x to both sides
5x+40=100
minus 40 both sides
5x=60
divide both sides by 5
x=12
the number is 12
Answer:
35 is the answer to #8 I believe.
A parallelogram is a shape with 4 sides where the 2 opposite sides are congruent or has the same measurements. The perimeter of a parallelogram is expressed as:
P = 2l + 2w
We take AD as the length, l, and AB as the width, w.
92 = 2(2w + 7) + 2w
92 = 4w + 14 + 2w
78 = 6w
w = 13 cm
l = 2w+7 = 33 cm
