Check the picture below.
they're at a 3:1 ratio, thus, 3 times.
Answer:
x = 14
Step-by-step explanation:
2(4x+1) + (5x-4) = 180
13x-2=180
x = 182/13 = 14
It is an isoceles triangle, so D = E
F = 66
D = E = 57
Answer:
assuming x2 is x^2:
f(x) = (x+4)^2 - 3
Step-by-step explanation:
1. move c to f(x) side
2. make sure a=1
3. (b/2)^2
4. add the solution of 3 on both sides
5. factor the right side using the shortcut
6. add c back to the other side
Ok so B is 78 - 26 = x
X is your answer
