(x+4)(x-2) as a triomial in standard form
2 answers:
x^2 + 2x - 8
just multiply (x+4)(x-2)
x times x = x^2
x times -2 = -2x
4 times x = 4x
4 times -2 = -8
-2x + 4x = 2x
Answer:

Answer:
a. x = total - $5
b. x = $6
c. x = $10
Step-by-step explanation:
a. pen + book = total
Let x = book
$5 + x = total
x = total - $5
b. pen + book = total
Total = 411
$5 + x = $11
x = $11 - $5
x = $6
c. pen + book = total
Total = $15
$5 + x = $15
x = $15 - $5
x = $10
