15. Find the product of (5x – 3) and (x3 – 5x + 2).
a) 5x4 – 3x3 + 25x2 – 5x – 6
b) 5x3 – 28x2 + 25x – 6
c) 5x4 – 3x3 – 25x2 + 25x – 6
d) 5x3 + 22x2 – 5x – 6

Answer:

B

Step-by-step explanation:

∠ 3 and ∠ 8 are alternate angles and are congruent, then

6x + 3 = 4x + 29 ( subtract 4x from both sides )

2x + 3 = 29 ( subtract 3 from both sides )

2x = 26 ( divide both sides by 2 )

x = 13 → B

im not shore if its right, i used a surface area calculator

Answer:

56ft

Step-by-step explanation:

Surface area is adding up all the sides multiplied by 2, so:

8 x 2 = 16ft

8 x 2 = 16ft

12 x 2 = 24ft

24ft + 16ft + 16ft = 56ft

Answer:

25

Step-by-step explanation:

The number line inequality will be true for the following condition given in this problem:

When a = 0 and c = -8.

On a number line, real numbers increase from left to right, meaning that:

Large negative numbers come before small negative numbers, which come before small positive numbers, and finally, come the large positive numbers.

For this problem, the inequality is:

c > b > a.

Which means that:

We have that b < -1, hence:

Then the conditions that make the statement b < -1 true are given as follows:

When a = 0 and c = -8.

Capacity of Matti's green house = 367.5 cubic feet

Step-by-step explanation:

Given:

Base Width and Length = 7 feet by 15 feet

Height of prism = 7 feet

Find:

Capacity of Matti's green house

Computation:

Capacity of Matti's green house = Volume of rectangular base[triangular prism]

Volume of rectangular base[triangular prism] = Area of triangular base x Height

Capacity of Matti's green house = [(1/2)(7)(7)][15]

Capacity of Matti's green house = [(1/2)(49)][15]

Capacity of Matti's green house = [(24.5)][15]

Capacity of Matti's green house = 367.5 cubic feet

Answer:

18.84feet

Step-by-step explanation:

Length of an arc = rtheta

radius r = 9feet

theta = SR= 120°

Convert theta to radians

theta = 120π/180

theta= 2π/3

Length of the arc = 9 * 2π/3

L = 18π/3

L = 6π

L = 6(3.14)

L = 18.84feet

Hence the length of the arc is 18.84feet

Answer:

B.

Step-by-step explanation:

Answer:

x = 61

Step-by-step explanation:

These 2 angles are supplementary which means they add up to 180:

2x - 6 + x + 3 = 180

3x - 3 = 180

3x = 183

x = 61

Answer:

40%  properties  are Semi-detached

Step-by-step explanation:

Given,

Percentage of Bungalow = 10%

Percentage of Detached properties = 30%

Percentage of Apartments = 20%

∴Total percentage of properties deducting the  semi-detached properties

= (10 + 30 + 20) %

= 60%

∴ Percentage of semi detached properties = (100 - 60) %

                                                                        = 40%

So, 40% properties are Semi-detached.

Answer:

$261.80 Net pay

Step-by-step explanation:

340 x 0.23 =   $78.20 in taxes

$340 - $78.20 =  $261.80 Net pay

Answer:

$261.8 Is how much you take home.

Step-by-step explanation:

(* is multiply)

In order to find the percentage of a value, you multiply the value by the percent. Think of 100% as a scale of 1 to 0.00, since 100% of something has all of it's value, so 50% would be 0.5

23% of 340 is 78.2 ( 340 * 0.23)

Subtract 340 by 78.2, and you get your net pay, 261.8

Another way to do this is subtract 100% by 23%.

so 1 - 0.23= 0.77, which is how much percent of that pay you get to keep

so 340 * 0.77 = 261.8

Step-by-step explanation:

Answer:

2x + 20 = -60

-20           -20

2x = -80

Divide by 2 on both sides.

X = -40

Answer:

-40

Step-by-step explanation:

2(x + 10) = -60

step 1 distribute the 2 to the x and 10

2 * x = 2x

2 * 10 = 20

we now have 20 + 2x = -60

step 2 subtract 20 from each side

20 - 20 cancels out

-60 - 20 = -80

we now have 2x = -80

step 3 divide each side by 2

2x / 2 = x

-80 / 2 = -40

we're left with x = -40
