Answer:
Step-by-step explanation:
<u>Cost of each item:</u>
- Pizza = $1.50, Hotdogs = $1.25
<u>Number of each item:</u>
- Pizza = x, Hotdogs = x + 20
<u>Total cost:</u>
- 1.25x + 1.5(x + 20) = 173
- 1.25x + 1.5x + 30 = 173
- 2.75x = 143
- x = 143/2.75
- x = 52
<u>Number of slices of pizza:</u>

Answer:
(y + 14)(y - 14)
Step-by-step explanation:
A difference of squares has the general form
a³ - b² and factors as
(a + b)(a - b)
Given
y² - 196
y² = (y)² ⇒ a = y and 196 = 14² ⇒ b = 14
y² - 196
= y² - 14² = (y + 14)(y - 14) ← difference of squares
Answer:
19 - 8√3
Step-by-step explanation:
(-4 + √2)^2
= (-4)^2 + 2(-4)(√3) + √3)^2
= 16 - 8√3 + 3
= 19 - 8√3
