Answer is C. multiply by 3 - square root 5
using a^2 - b^2 = (a + b)(a - b)
Answer:
6(8+3x)
Step-by-step explanation:
48+18x
We can factor out an 6 from each term in the expression
6(8+3x)
Answer:
Step-by-step explanation:
In similar polygons, corresponding sides are in same proportion

Cross multiply
7*(4x-3)=3*(x+1)
28x - 21 = 3x + 3
28x - 3x - 21 = 3
25x = 3 + 21
25x = 24
x = 24/25
x = 0.96
Scale factor = 7 : 3
200t + 8t^3 - 80t^2
8t(25 + t^2 - 10t) ....rearrange
8t(t^2 - 10t + 25)
8t(t - 5)(t - 5)
8t(t - 5)^2 <==
