(6 • 2 - 2x + 16) + (4 • 2 + 7x - 55)
(-2x + 16 + 6 • 2) + (7x - 55 + 4 • 2)
(-2x + 16 + 12) + (7x - 55 + 8)
-2x + 28 + 7x - 47
-2x + 7x + 28 - 47
5x + (-19)
5x - 19

Employees of a landscaping company built a retaining wall. They used brick to make the top 2/3 of the wall. The wall is 8and 1/2
IgorC [24]

Answer:

Height of the brick portion of the wall is 5.61 feet.

Step-by-step explanation:

Employees of the landscaping company used brick to build the top 2/3 of the wall. The total dimensions of the wall are 8 and 1/2 * 2 and 3/4 feet. So the height of the wall = 8 and 1/2 feet or in other words 8.75 feet.

Height of the brick portion of the wall = 2/3 * 8.5 = 0.66 * 8.5 = 5.61 feet

So the height of the brick portion of the wall is 5.61 feet.

Non brick portion of the wall is 8.5 - 5.61 = 2.89

Juanita begins to factor an expression as shown. x2+3x−18=(x+)(x−) What numbers should be placed in the boxes from left to right
stich3 [128]

Answer:

Option A is the correct answer.

Step-by-step explanation:

Here we need to factorize  x²+3x−18

The coefficient of x is 3 and the constant is -18

Which means

           The sum of factors is 3

           The product of factors is -18

The factors satisfying are  6 and -3

Here the factors are given in the type (x+)(x−)

     So the value after plus is 6 and value after - is 3

Option A is the correct answer.
