Answer:
third one passes through the slope .
the formula for volume of sphere is 4/3||r^3
diameter=2radius
in the formula we need to have radius but we have been given diameter so we convert diameter to radius
d=2r
r=d/2
9.5÷2
4.75
(a+b)(a-b)=a^2 - b^2
so
<span>(4x-7)(4x+7) = 16x^2 - 49
answer
</span>16x^2 - 49
a square number has and odd amount of numbers but 5to the power of 9 has an even amount of numbers
5×5×5×5×5×5×5×5×5
1/4x - 10 = -50
1/4x = one forth of a number
-10 is decreased by 10
= -50 means is -50
