Answer:
The graph and the number line in the attached figure
Step-by-step explanation:
we have

Solve for x
subtract 7 both sides


Divide by -2 both sides
Remember
When you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol
so

The solution is the interval (-8,∞)
All real numbers greater than -8
In a number line the solution is the shaded area at right of x=-8 (open circle)
The graph and the number line in the attached figure
Answer:

Step-by-step explanation:
The given expression is 26.48. We need to write the equivalent expression for it. There are two numbers after decimal. It means that we can divide 2648 by 100 i.e.

We know that, 2648 = 662 × 4 and 100 = 25 × 4

Hence,
is the equivalent expression.
Answer:
Height = w + 4
Step-by-step explanation:
3w³ + 16w² + 16w = w (3w² + 16w + 16)
= w (3w + 4) (w + 4)
The length of a rectangular prism is 4 more than 3 times the width, w
L = 3w + 4
R prism volume = L x W x H
Height = w + 4
