2. a. - 2a + 10

3. d. 13x - 45

4. 2c-7d

5. b. -2z - 12

Step-by-step explanation:

1.  4(x+10)  = 4x+4*10 = 4x+40

C


2.  -2(a - 5) = -2*a -2*-5 = -2a+10

A

Each side of the square below is 8 inches. A triangle inside of a square. The top of the triangle divides a side of the square i
dmitriy555 [2]

The probability that a point is chosen at random in the square is in the blue region is 0.8.

<h3>What is Probability?</h3>

The probability helps us to know the chances of an event occurring.

\rm{Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}

As we know that the area of the shaded region is the sum of the area of triangle A and the area of triangle B. Therefore, the area of the blue shaded region is,

\text{Area of shaded region} = (\dfrac{1}{2} \times 8 \times 8) + (\dfrac{1}{2} \times 4 \times 8)

                                  = (32) + (16)\\\\= 48\rm\ in^2

The area of the square can be written as,

\text{Area of Square} = \rm(Side)^2 = 8^2 = 64\ in^2

Now, the probability that a point is chosen at random in the square is in the blue region can be written as,

\rm{Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}\\\\

\rm Probability = \dfrac{\text{Area of blue region}}{\text{Area of square}}\\\\Probability = \dfrac{48}{60} = 0.8

Hence, the probability that a point is chosen at random in the square is in the blue region is 0.8.

The length of a rectangle is 5 inches more than 3 times the width. If the area of the rectangle is 68 square inches, what is the
Paladinen [302]

Answer:

Width=4, and Length=17

Step-by-step explanation:

first you will make a variable for the width which i will say is x

now make it an equation (3x+5) (x) = 68

then solve 3x^2+5x=68

then 3x^2+5x-68=0

then x=4

then you have to substitute so 3(4)+5= 17 and 4
