Answer:
Explanation:
Find x:
f(x) = g(x)
x^2+2x-1 = 5x+3
x^2+2x-5x-1-3 = 0
x^2-3x-4 = 0
(x-4)(x+1) = 0
=> x-4 = 0 => x = 4
=> x+1 = 0 => x = -1
Find f(-4):
(-4)^2 + 2(-4) - 1
= 16 - 8 - 1
= 7
Find g(9):
5(9) + 3
= 45 + 3
= 48
The answer is D
it could he written 1/3 times d which represents the number of raisins David it. Yet, it 1/3 times d are multiplied together, the simplest form of the expression is d over 3.
Width of the rectangle =
Length of the rectangle =
Solution:
Area of the rectangle =
Width of the rectangle = greatest common factor of
Factor of =
Factor of =
Factor of =
Greatest common factor of
=
Width of the rectangle
Area of the rectangle = length × width
Divide by 5k² on both sides.
Cancel the common factor 5k², we get
Switch the sides.
Length =
Width of the rectangle =
