answer is 2
Step-by-step explanation:
2 times 2 equals 4
and 8 divided by 4 equals 2
2(b+3) = 2
2b + 6 = 2 ( -6 )
2b = -4 ( / 2)
b = -2
Answer:
tge radius is half the diameter so 1/2 of 3 1/2 =1.75 or 1 3/4
Eliminate the exponent
2^3=8
9^3=729
The simplified answer would be 8/729.
Hope this helps!
Answer:
a=8
Step-by-step explanation:
We can use ratios of similar triangles to solve
The smaller triangle has sides a and 12 and the larger triangle has sides a+a+4 and 12+18 which combine to 2a+4 and 30
a 2a +4
--------- = -----------
12 30
Using cross products
30a = 12(2a+4)
30a = 24a +48
Subtract 24a from each side
30a -24a = 24a-24a +48
6a = 48
Divide each sdie by 6
6a/6 =48/6
a =8
