150%. since you already have 6, that's 100%. the extra 3 is half of the 6, meaning that it would be 50%
Answer:
x=8
Step-by-step explanation:
add 4 to both sides
divide 40 by 5
then you are left with x=8
Answer:
28.27
Step-by-step explanation:
A=(1/4) πd^2
8(11 + 2r) = 126r + 3
first open the parenthesis
88 + 16r = 126r + 3
88 - 3 = 126r - 16 r
85 = 110r
divide both-side of the equation by 110
85/110 = r
r= 17/22
since triangles are similar
4/x = 7x/7
=》 4/x = x
=》x^2 = 4
=》 x = 2
for right triangles a^2 = b^2+c^2
DF^2 = 7^2+2^2 = 53
=》 DF = 7.28
perimeter of DEF = 7 +2+7.28 = 16.28
