Answer:
18+2x
Step-by-step explanation:
Let the number be x.
Translate: 2x + 18 = x - 4.
Subtract x from each side: x + 18 = -4.
Subtract 18: x = -22.
Check: 2(-22) + 18 = -44 + 18 = -26; -22 - 4 = -26.
8 increased by twice a number = 18+2x

f(x)=-2(x+1)^2-12 in the form f(x) =ax^2+bx+c
Answer:
[tex] \boxed{ f(x) = -2x^2 - 4x - 14 } [/tex]
Step-by-step explanation:
f(x) = -2(x+1)²-12
f(x) = -2(x²+2x+1) - 12

We first have to find 2 pairs of sides that proportional.
35/20=42/24=7/4
and 21/b should be 7/4 as well because if we want the triangles to be similar the sides should be in proportion.
21/b=7/4
84=7b
b=12
Done!
