Step-by-step explanation:
Answer: 4
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
13. (3/8)*q + 12 = 36
3q/8 = 24
3q = 192
q = 64
14. 3 - (3/4)n = 9
-3n/4 = 6
-3n = 24
n = -8
15. (7/9)v + 2 = 23
7v/9 = 21
7v = 189
v = 27
16. 7 + (1/8)l = -2
l/8 = -9
l = -72
17. (v/-3) + 8 = 22
v/-3 = 14
v = -42
18. 8x - 16 + 8x = 16
16x = 32
x = 2
19. 12a - 14a = 8
-2a = 8
a = -4
20. 7c - 8 - 2c = 17
5c = 25
c = 5
21. 6 = -y + 42 - 2y
-36 = -3y
y = 12
22. 16 + 8r - 4r + 4 = 24
20 + 4r = 24
4r = 4
r = 1
Answer: x² - x - 12
Step-by-step explanation: When multiplying two binomials together, we can use the F.O.I.L. method.
<em>First, Outer, Inner, Last</em>.
We take the product of the first terms which is x² plus the product of the outer terms which is -4x plus the product of the inner terms which is 3x plus the product of the last terms which is -12.
So we have x² - 4x + 3x - 12.
Simplifying from here by combing the middle terms, we have x² - x - 12.
Pay very close attention to your positives and negatives as you F.O.I.L. because this is the area where most mistakes occur.
