Answer:
23
Step-by-step explanation:
Evaluate f(- 2) then substitute the value obtained into g(x)
f(- 2) = 3(- 2)² + 2(- 2) - 1 = 3(4) - 4 - 1 = 12 - 5 = 7 , then
g(7) = 4(7) - 5 = 28 - 5 = 23
Step-by-step explanation:
x³ - 4x² + 3x
= x(x² - 4x + 3)
= x(x -3)(x - 1)
× = 0, 1, 3
The answer for this will be
2a(1-2a ²+3bc)
Answer:
k = 7
Step-by-step explanation:
Step 1: Write equation
-18 = 5 - (6k - 19)
Step 2: Solve for <em>k</em>
<u>Distribute negative:</u> -18 = 5 - 6k + 19
<u>Combine like terms:</u> -18 = -6k + 24
<u>Subtract 24 on both sides:</u> -42 = -6k
<u>Divide both sides by -6:</u> k = 7
Step 3: Check
<em>Plug in k to verify it's a solution.</em>
-18 = 5 - (6(7) - 19)
-18 = 5 - (42 - 19)
-18 = 5 - 23
-18 = -18
Answer:
7.2 cm
Step-by-step explanation
The area of a rectangle is calculated by multiplying the width and the length together. Therefore:
13 multiplied by x = 93.6
x = 93.6 divided by 13
x= 7.2
