Answer:

| 4x - 8 - 6 | < 8
1.5 < x < 5.5

Step-by-step explanation:

<h3>Area of the figures</h3>

Rectangle:

4(x - 2) = 4x - 8

Triangle:

1/2*3*4 = 6

The difference between the areas, inequality:

| 4x - 8 - 6 | < 8

Solution

| 4x - 14 |< 8
1. 4x - 14 < 8 ⇒ 4x < 22 ⇒ x < 22/4 ⇒ x < 5.5
2. 4x - 14 > -8 ⇒ 4x > 6 ⇒ x > 6/4 ⇒ x > 1.5
x = (1.5, 5.5)

Find the measure of angle ABC. A. 124 B. 97 C. 56 D. 51

Airida [17]

Answer: Last Option

Step-by-step explanation:

By definition the sum of the internal angles of a triangle must always be equal to 180 °.

This means that:

$32 + (2x-15) + (x-5)=180$

Now we solve the equation for the variable x

$32 + 2x-15 + x-5=180$

$2x+x +32-15-5=180$

$3x +32-20=180$

$3x +12=180$

We subtract 12 in both barks of the equation

$3x +12-12=180-12$

$3x=168$

Divide by 3 on both sides of the equation

$\frac{3}{3}x=\frac{168}{3}$

$x=\frac{168}{3}$

$x=56$

Finally the measure of angle ABC is: (56-5)° = 51°

Susan incorrectly factored the expression below. 12a − 15b + 6 3 (4a + 5b + 3)

hichkok12 [17]

Answer:

3(4a−5b+2)

Step-by-step explanation:

The answer should have originally been 3(4a-5b+2)

3(4a+5b+3)= 12a+15b+9 which is incorrect.
