Answer:
3. Option No. 2:
6x + 2y = 22
3x + 3y = 18
4. Option No. 2:
$2.50
Step by step explanation:
4. 6x + 2y = 22
(3x + 3y = 18) * 2
- Negate
6x + 2y = 22
6x + 6y = 36
2y - 6y = 22 - 36
-4y = -14
y = -14/-4
y = 3.5
An order of onion rings = $3.50
- Substitute to find for x
6x + 2(3.5) = 22
6x + 7 = 22
6x = 22 - 7
6x = 15
x = 15/6
x = 2.5

Answer:
a² - 5a - 36
Step-by-step explanation:
(a - 9)(a + 4)
each term in the second factor is multiplied by each term in the first factor, that is
a(a + 4) - 9(a + 4) ← distribute parenthesis
= a² + 4a - 9a - 36 ← collect like terms
= a² - 5a - 36
