select the two binomials that are factors of this trinomial.
x^2+4x-32
a. x-8
b. x+8
c. x+4
d. x-4

Answers

Answer:

b and d

Step-by-step explanation:

Sum = 4

Product = -32

Factors = 8 , (-4)

x² + 4x - 32 = x² + 8x - 4x - 4*8

                   = x(x + 8) - 4(x + 8)

                  = (x + 8)(x - 4)

Answer:

  (d)  scale factor 1/2; center: the origin

Step-by-step explanation:

Consider point B(2, 6). That gets dilated to make point D(1, 3). These coordinates are different, so the center of dilation is not point B. The ratios of the coordinates of D to B are 1/2 and 3/6 = 1/2. This is the scale factor k. (The coordinates of other corresponding points also have the same ratio.)

  k = 1/2; dilation center: the origin

What is an Arithmetic operation?

Combining operands with a single arithmetic operator specifies an arithmetic operation. The built-in functions ADD, SUBTRACT, DIVIDE, and MULTIPLY can also be used to specify arithmetic operations. in general, we use PEMDAS for calculating various arithmetic operations.

Given 25% of the marbels ar red. and also given 45 marble are red.

Hence Total marble will be,

Total marbles = [tex]\frac{45* 100}{25}[/tex] = 180.

Therefore the total number of marbles in the jar is 180.

Step-by-step explanation:

Given data

1/5 full holds 16 liters

1/2 full barrel will hold???

Let 1/2 full barrel hold x liters

1/5 holds 16 liters

1/2 will hold x

Ewan has a mango farm that is 75 feet X
50 feet, and he also purchases a 20 feet X
10 feet plot of land. Find the total area of
the farm.

Answers

Answer:

3950 feet squared

Step-by-step explanation:

So first you have to multiply 75 by 50, so that is 3750.

Next you have to multiply 20 by 10 and you get 200.

Finally you had both 3750 and 200 in order to get 3950 and that is why the total area of the farm is 3950 feet squared.

then subtract to get x or y

     x+y=3

- (-3x+y=-17)

       4x=20

         x=20/4

         x=5

then sub in the x value into one of the equations

for x+y=3

    (5)+y=3

Answers

Answer:

8 Hours

Step-by-step explanation:

Since 4 painters painting one house takes 14 hours, then one person would take 56 hours to paint the whole house. Hence, 4 x 14 = 56. If 7 people painted the house, then 8 hours would be needed since 56 / 7 = 8.

4 people x 14 hours = House

56 hours = House

56 hours is required to paint a house.

7 people x H hours=  House

7 people x H hours = 56

(7 people x H hours)/ 7 = 56 / 7

You divide 7 on both sides to isolate H on one side.

H hours = 8

So H = 8 which is the amount of hours needed.

b. Does the solution of your equation solve the original problem? Explain.

Answers

Answer:

a) x = 34

b) yes, it checks out

Step-by-step explanation:

2x - 5 = 3(4 + 1/2x)

multiply both sides by 2 to eliminate fraction

2[2x - 5 = 3(4 + 1/2x)] = 4x - 10 = 24 + 3x

x - 10 = 24

x = 34

check

2(34) - 5 = 3(4 + 34/2)

68 - 5 = 3(4 + 17)
