Answer:
20
Step-by-step explanation:
3x + x + 100 = 180 (sum of angles on a straight line)
4x = 180-100
4x=80
divide both sides by 4
x=20
Equations are steeper when their slope's positive value is higher (ignore negatives when determining how steep a slope is). The slope is the value in front of x. If there isn't a value in front of x, then it is assumed to be 1.
Answer:
The answer is option B.
Step-by-step explanation:
<span>(4d-4)(3d-2)=12d^2 + []d + 8
Using FOIL method:
4d x 3d = 12d^2
4d x -2 = -8d
-4 x 3d = -12d
-4 x -2 = 8
Adding common terms, we have:
-8d + -12d = -20 d
The missing coefficient is -20.</span>
