a fraction in simplest form.

Answer:

x=−3 or x=−7

Step-by-step explanation:

Let's solve your equation step-by-step.

3(x+5)2−12=0

Step 1: Simplify both sides of the equation.

3x2+30x+63=0

Step 2: Factor left side of equation.

3(x+3)(x+7)=0

Step 3: Set factors equal to 0.

x+3=0 or x+7=0

x=−3 or x=−7

Answer: x=-3 and x=-7

Answer:

140 inches

Step-by-step explanation:

Find the area of the square.

4 + 10 = 14 (Length)

11 + 4 = 15 (Breadth/Width)

Area = 14 x 15 = 210 inches

Find the area of the 2 unshaded squares in the square.

Area of square at the top = 4 x 4 = 16 inches

Area of square at the bottom = 6 x 9 = 54 inches

Add the 2 squares of the area together.

16 + 54 = 70 inches

Now deduct the area of the huge box by the area of the 2 unshaded squares.

210 - 70 = 140 inches

Step-by-step explanation:

= 6x² - 11x - 10

= 6x² + 4x - 15x - 10

= 2x (3x + 2) - 5 (3x + 2)

= (2x - 5) (3x + 2)

x = 5/2 & -2/3

Answer:

x ≈ 30.9 (Choice D)

Step-by-step explanation:

We can use cosine for solving this question:

cos (61°) = 15 / x

x = 15 / cos (61°)

x = 30.93998011

x ≈ 30.9 (Choice D)

Answer:

Answer:

  x = 8

Step-by-step explanation:

The marked angles are alternate interior angles, so are congruent.

  8x -4 = 60

  8x = 64 . . . . . . . . . . add 4 to both sides

  x = 64/8 = 8 . . . . . . divide both sides by 8

The value of x is 8.

Answer:

Step-by-step explanation:

1st draw 3 circles where each center is on one of the points,  and the other side , the drawing side of the compass is on another point.. the draw the circle ... do that for each point... there will be one point.. where all three cross some where in the middle.. put the point of your compass on that point.. and then put the drawing side on any one of the points... all 3 will now be on the circle.. draw it.. :)  

The circle can be constructed through points X, Y, and Z by drawing a side on any one of the points.

It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)

As we can see in the picture.

The construction of a circle through three points can be done:

First, draw three circles with each center on one of the points and the drawing side of the compass on another point.

There will be one place where all three intersect somewhere in the middle, but the point of your compass should be on that point, and then put the drawing side on any one of the points.

Thus, the circle can be constructed through points X, Y, and Z by drawing a side on any one of the points.

Answer:

96º

Step-by-step explanation:

The sum of a triangle's angles is 180. We can find t by subtracting 58 and 38 from 180. 180-58-38=84. x and t and supplementary angles, so x is 180-t which is 180-84=96º.

Answer:

A

Step-by-step explanation:

Area of the unshaded region = 95/360  * 3.14 * (5*√2)^2

Area of the unshaded region = 95/360 * 3.14 * 50

Area of the unshaded region = 41.43

Area of the entire circle = pi r^2

Area of the entire circle = 3.14 * (5√2)^2

Area of the entire circle = 157

Area of the shaded part = The whole circle's area - the unshaded part

Area of the shaded part = 157 - 41.42

Area of the shaded part = 115.57

I have no idea what set builder is, so I'll just solve it if that's okay.

t-3>-8

First, to cancel out -3, you need to add it to both sides.

Answer:

42

Step-by-step explanation:

70 minus 40 percent equals 42

Answer:

x = 7

Step-by-step explanation:

4x - 9 = 2x +5        add 9 from both sides

4x = 2x +14            subtract 2x from both sides

2x = 14.                   divide both sides by 2

x = 7

Answer:

x = 7

Step-by-step explanation:

Rewrite equation

4x - 9 = 2x + 5

Add 9 on both sides

4x -9 +9 = 2x + 5 + 9

Simplify

4x = 2x + 14

Subtract 2x on both sides

4x - 2x = 2x + 14 - 2x

2x = 14

Finally divide both sides by 2

2x/2 = 14/2

x = 7

Answer:

86%

Step-by-step explanation:

28 were placed on suspension

200 are total (including that 28)

not placed on suspension are the rest, so 200-28=172

172 out of 200 = 86% not placed on suspension

Answer:

86% Pls consider marking brainliest if correct.

Step-by-step explanation:

Okie lets see

In all : 200

Removed : 28

To find percentage : 200-28/200

200 - 28 = 172

172/200 = (172/2)/(200/2)

I did this because 200 is 100x2, and because percentage is over 100

172/2 = 86

200/2 = 100

86/100 = 0.86 = 86%

Answer:

C, D

Step-by-step explanation:

In a triangle, the length of any side must be least than the sum of the lengths of the other 2 sides.

That means

3x < 19 + 6

3x < 25

x < 25/3

x < 8 1/3

Answer: C, D

Answer:

66.03 so 70

Step-by-step explanation:

since hypotunees has no value it cancels.

aso it leaves with an adjacent and oppisite

using trig function you will get

tan(x)=(9/4)

inverse tan to get x on its own

(x)=tan^-1(9/4)

put that on the calculater and you will get the angle

therefore

(x)=66.04 round it the nearest ten which is

Answer:

28 hours

Step-by-step explanation:

6x28=168

To earn atleast $168, Hermes should do babysit for atleast 28 hours.

Inequality is just like an equation showing relationship between two or more variables but this is expressed in greater than ,less than form.

It defines a range of value of the relationship.

We have been given that Hermes earns $6 per hour for babysitting and he wants to earn atleast $168 for a new video game. We have to calculate the minimum number of hours that he should do babysit in order to earn $168.

We know that total revenue will be number of hours* payment of 1 hour.

let the number of hours that he does babysit is x.

The inequality will be :

6x>168

x>168/6

x>28

Hence to earn atleast $168 he should work for atleast 28 hours.
