The equivalent expression on expanding -1/4 (-8x + 12y) is 2x - 3y
<h3>Expansion of expression</h3>
Expansion of expression can be carried out using the distributive rule a shown:
A(B + C) = AB + AC
Note that <u>A is distributed over B and C</u>
Given the expression
-1/4 (-8x + 12y)
-1/4(-8x) - 1/4(12y)
2x - 3y
Hence the equivalent expression on expanding -1/4 (-8x + 12y) is 2x - 3y

Step-by-step explanation:
I am not sure why you would need to know this but just use a calculator
The possible midpoints for PQ are
c. -2 and 6
explanation:
coordinate of midpoint is 0.5(P+Q)=0.5(2+x)=1+0.5x
PQ=8 so |x-2|=8
x-2=8 or x-2=-8
so x<span>=10 or x=-6
coordinate of midpoint= 1+0.5x
x=10 we get 6 and x=-6 we get -2</span>
Answer:
v ≈ 113.09
Step-by-step explanation:
v = πr^2*h
v = π*2^2*9
v = π*4*9
v = π*36
v = 113.097335529
hope this helps :)
