Answer:
-5 < x < 5
Step-by-step explanation:
|x| < 5
This can be split into two cases: x < 5 and -x < 5 because |x| could be either x or -x depending on whether x is positive, negative, or 0. Solving the second one we get x > -5 so the answer is -5 < x < 5.
Answer:
51 ft
Step-by-step explanation:
y-12 = -1/4 (x-3) = 51 ft
Answer:
X=84/21
Step-by-step explanation:
X/14=6/21
X=(6/21)(14/1)
X=84/21
Step-by-step explanation:
So the way you do this is if it says 'Find AC' and on the angle you see different letters connect then on the lines and name the angle
More that 90°= Obtuse
90° angle= 90° angle
Less than a 90° angle= isosolines angle

Answer: (c * d)(x) =
4x^3 + 18x^2 - 10x</h3>
Work Shown:
I'm assuming the dot means multiplication. If so, then,
(c * d)(x) = c(x)*d(x)
(c * d)(x) = [ c(x) ] * [ d(x) ]
(c * d)(x) = (4x-2)(x^2+5x) .... substitution
(c * d)(x) = 4x(x^2+5x) - 2(x^2+5x) ... distribute
(c * d)(x) = 4x(x^2)+4x(5x) - 2(x^2)-2(5x) ... distribute again
(c * d)(x) = 4x^3 + 20x^2 - 2x^2 - 10x
(c * d)(x) = 4x^3 + 18x^2 - 10x
