Can someone please help me with these 5 questions first one. -5x + 2 - 8x + 9
second one. 5x + 8 + 2 + 3x
third one. 1x + 9x + 4 + 4
fourth one. 6 - 7x + 9 - 2x
last one. 14 - 4x + 3 - 1x

1. -13x + 11

2. 8x + 10

3. 10x + 8

4. -9x + 15

5. -5x + 17

Step-by-step explanation:

In the first problem, you have to do -5x + -8x which is -13x. Then you add 2+9 which is 11. You will get the expression -13x + 11.

In the second problem, you have to do 5x + 3x which is 8x. Then you add 8 + 2 which is 10. You will get the expression 8x + 10.

In the third problem, you have to do 1x + 9x which is 10x. The. you add 4 + 4 which is 8. You will get the expression 10x + 8.

In the fourth problem, you have to do -7x + -2x which is -9x. The. you add 6 + 9 which is 15. You will get the expression -9x + 15.

In the last problem, you have to do -4x -1x which is -5x. The. you add 14 + 3 which is 17. You will get the expression -5x + 17.

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

complete the steps to find the area of the trapezoid.

area of rectangle = 256   square units

area of triangle 1 = 24  square units

area of triangle 2 = 16  square units

area of triangle 3 =   96 square units

area of trapezoid = 120  square units
