Replacing for values of a and c in the equation
a=20
c=8
m=4a+2c
m=4(20)+2(8)
m=80+16
m=96
His answer works ... it gives 150, which is the same as (60 + 90) ... but he didn't deliver exactly what the problem asked for.
It asked for the <u>GCF</u> to be outside the parentheses, and he put '3' there.
'3' is certainly one common factor of 60 and 90, but it's far from being the
greatest one.
The GCF of 60 and 90 is actually 30 . So the absolutely positively technically correct response to the instructions in the problem would be 30(2 + 3).
Answer:
D
Step-by-step explanation:
when flipping and turning the second triangle, so that it is oriented as the first triangle (we see DE corresponds to AB - consider at what corner point the right angle is : at A and at D; DF corresponds to AC, EF corresponds to BC), we see immediately that BCA is the same sequence of corners as the corresponding EFD.
I believe it is 60 inches
