Answer:
x = 8/5
Step-by-step explanation:
first multiply both side by -1, it makes both side positive
1x/2 = 4/5
now multiply both sides by 2 to get the x by itself
x = 8/5
if they want improper fraction x = 1
Answer:
3
Step-by-step explanation:
Circumference = , where r is radius, and d is diameter
d=113/3.14=35.987, which is approximately 36
At 12 yards per hour, it will take 36/12=3 hours
Answer:
b. x² + 8x + 12 =
1. use the factoring X (see attachment)
2. 6 x 2 = 12; 6 + 2 = 12
3. (x + 6)(x + 2) = 0
4. x = -6, -2
c. x² + 13x + 12 =
1. 12 x 1 = 12; 12 + 1 = 13
2. (x + 12)(x + 1) = 0
3. x = -12, -1
c. x² + x - 12 =
1. 4 · (-3) = -12; 4 - 3 = 1
2. (x +4)(x - 3) = 0
3. x = -4, 3
f. x² + 15x + 36 =
1. 12 x 3 = 36; 12 + 3 = 15
2. (x + 12)(x + 3) = 0
3. x = -12, -3
hope this helps :)
