The solution to the expression using the FOIL method is x⁴ - 6x² + 8
<h3>How to evaluate the expression using FOIL?</h3>
From the question, we have the following parameters that can be used in our computation:
(X2-2)(x2-4)
Rewrite the expression properly
So, we have
(x² -2)(x² - 4)
The FOIL method states that: First, Outside, Inside, and Last
Using the acronym as a guide, we have
(x² -2)(x² - 4)
Expand the expression
This gives
(x² -2)(x² - 4) = x²(x² - 4) -2(x² - 4)
Expand the brackets
So, we have the following representation
(x² -2)(x² - 4) = x⁴ - 4x² -2x² + 8
Collect the like terms
This gives
(x² -2)(x² - 4) = x⁴ - 4x² -2x² + 8
Lastly, we evaluate the like terms
(x² -2)(x² - 4) = x⁴ - 6x² + 8
Hence, the solution to the equation is x⁴ - 6x² + 8

A. your equation would be 17 + 8.50X
number of additional large pizzas equation cost
1 17 + 8.50(1) $25.50
2 17 + 8.50(2) $34.00
3 17 + 8.50(3) $42.50
b. will get back to you
c. 17 + 8.50 (20) = 187 $187
d. $34 X 5 = $170 17 + 8.50 (14) = $136 170 - 136 = $34 saved
Answer:
f(x)=10+0.25x
she can put maximum 20 words
Step-by-step explanation:
f(x)<=15
10+0.25x<=15
0.25x<=5
x<=20
First half is negative and second is positive
