(a+b)(a-b)=a^2 - b^2
so
<span>(4x-7)(4x+7) = 16x^2 - 49
answer
</span>16x^2 - 49
So the formula for a volume of a sphere is 4/3 times pi times the radius cubed.
step one: 4/3 times 3.14 = 4.18666666667
Step two: then you cube 8.5 and get 592.45
the final answer is 2,480.3906
Answer:
6³ = 216 cubes
Step-by-step explanation:
she needs six layer of 6x6 = 36 cubes
Answer:
No
Step-by-step explanation:
The slope of the equation is y = 2x + 3 is 2.
Find the slope of the points.
m = y₂ - y₁ / x₂ - x₁
m = 1 - 7 / 1 - (-2)
m = -6 / 3
m = -2
The same slope will happen if you also calculate for the third point.
As you can see. The slopes are not the same for one is rising (positive) while the other is fall (negative).
