Solve the equation 3|4x+3|+8=17

Mathematics
1 answer:
pentagon [3]3 years ago
3 0

Answer:

x=-3/2 or x=0

Step-by-step explanation:

Subtract 8 from both sides

3|4x+3|+8-8=17-8

Simplify

3|4x+3| = 9

Divide both sides by 3

3|4x+3|/3 = 9/3

Simplify

|4x+3|=3

Apply absolute rule

4x+3=-3 or 4x+3=3

Solve

x=-3/2 or x=0

A triangle has side lengths of 7 in., 9 in., and 11 in. Determine whether this is a right triangle and why.
Harlamova29_29 [7]

Answer:

Not a right triangle.  See below for my reasoning.


Step-by-step explanation:

If this is a right triangle, then the sum of the squares of the two shorter sides will equal the square of the longest side:  7^2 + 9^2 = 11^2 => 49 + 81 = 121   But this is false.
