Answer:
Area = 6x - 6
Step-by-step explanation:
Given:
Height = 2x - 2
Base = 6
Required:
Area
Solution:
Area of triangle = ½*b*h
Area of the triangle = ½*6*(2x - 2)
Area = 3(2x - 2)
Apply distributive property
Area = 6x - 6
Well now she has $4.25 lol. She had $4 then, now she has $4.25.

Answer: (c * d)(x) =
4x^3 + 18x^2 - 10x</h3>
Work Shown:
I'm assuming the dot means multiplication. If so, then,
(c * d)(x) = c(x)*d(x)
(c * d)(x) = [ c(x) ] * [ d(x) ]
(c * d)(x) = (4x-2)(x^2+5x) .... substitution
(c * d)(x) = 4x(x^2+5x) - 2(x^2+5x) ... distribute
(c * d)(x) = 4x(x^2)+4x(5x) - 2(x^2)-2(5x) ... distribute again
(c * d)(x) = 4x^3 + 20x^2 - 2x^2 - 10x
(c * d)(x) = 4x^3 + 18x^2 - 10x
Answer:
23
Step-by-step explanation:
First of all substitute x with g(x) on the expression of f(x)
; (f.g)(x) = -4(2x - 6) + 7
; (f.g)(x) = -8x + 24 + 7
Then substitute the value of x with the value 1...as the question asks yu
; (f.g)(1) = -8(1) + 24 + 7
; Hence (f.g)(1) = 23
