$3x^2-(-2x^2)+5x-(-6x)-6-(7)=5x^2+11x\text{ - 13}$

Therefore, the correct answer is:

$2)5x^2+11x\text{ - 13}$

You need to find the width of the stream you cannot measure the width directly so you draw a diagram showing lengths that you ca

kap26 [50]

You can set up proportions to find the width of the stream.

6/7.5=x/28

Cross multiply and solve for x.

168=7.5x

Divide by 7.5

x=22.4 ft

The stream is 22.4 ft wide

Question 7 of 10

Ganezh [65]

Answer:

Option B

Step-by-step explanation:

Given Equation :

$\qquad \sf \dashrightarrow \: 3(4x+3) = 2x - 5(3 - x) + 2$

Using distribute property:

$\qquad \sf \dashrightarrow \: 12x + 9 = 2x - 15 + 5x + 2$

Adding the like terms we get :

$\qquad \sf \dashrightarrow \: 12x + 9 = 2x + 5x - 15 + 2$

$\qquad \sf \dashrightarrow \: 12x + 9 = 7x - 13$

Transposing the variables on the right side and constant terms on the left side :

$\qquad \sf \dashrightarrow \: 12x - 7x = - 13 - 9$

$\qquad \sf \dashrightarrow \: 5x = - 22$

Dividing both sides by 5 :

$\qquad \sf \dashrightarrow \: \dfrac{5x}{5} = \dfrac{ - 22}{5}$

$\qquad \bf \dashrightarrow \: x = \dfrac{ - 22}{5}$
