Answer:

Step-by-step explanation:

Answer : 12cm^2

Step-by-step explanation:

A = bh/2

A = 12 cm^2

Answer:

Look at the image

Step-by-step explanation:

18 + 4(m - 3) + 4m

18 + 4m - 12 + 4m

The last graph (The last picture)

Answer:

The Last Graph

Step-by-step explanation:

To match up the graph I used the desmos online graphing calculator. I put the equation into the graphing calculator and it showed me how the graph was supposed to look like. I then matched the correct answer choice with the graph on desmos and got the last answer as the correct graph. There is many ways that you can do something like this but I took the easy route and used a graphing calculator.

Answer:

Isosceles Triangle; Acute Triangle

Step-by-step explanation:

Review your definitions of the different types of triangles:

acute triangle- a triangle that has three acute (less than 90 degrees) angles

obtuse triangle- a triangle that has an obtuse (greater than 90 degrees) angle.

right triangle- a triangle that had one right (90 degrees) angles

isosceles triangle- a triangle with two congruent sides and one unique side and angle.

equilateral triangle-  a triangle with three congruent sides and three congruent angles.

scalene triangle- a triangle with no congruent sides and no congruent angles.

With these definitions, we can classify ΔPQR as an isosceles acute triangle.

Step-by-step explanation:

cause if you count it he is closer

he has 70 and the others are like in the hundreds soo Elliot highest Ruth second Frankie has 80 more to read and then Haden has 286 more to read

Answer:

ruth  88/220  0.45 = 45%

hayden 117/260 0.4 = 40%

frankie  165/300  0.56 =56%

Answer:

D

Step-by-step explanation:

We are dealing with system of equations and can use graphing, elimination, or substitution. However, the equation is set up in a way such that it will be easier to use elimination. You can add the two equations and in doing so you will see the x and -x cancel out. The remaining equation is 2y = 0. So, y = 0. Substitute that into one of the equations and you get that x = 3. Therefore your answer is "D".

Step-by-step explanation:

Answer:

x=-20

Step-by-step explanation:

1. Expand 3(x+8) :  3x+24

2.Expand -3(7-1/4x):    -21*3/4x

3. 3x+24= -21*3/4x

4.Subtract 24 from both sides

3x+24-24= -21*3/4x-24

5.3x= 3/4x-45

6.Subtract 3/4 from both sides

3x-3/4= 3/4x-45-3/4

7.9/4x=-45

8.Multiply both sides by 4

9/4x*4=-45*4

9.9x=-180

10.Divide both sides by 9

9x/9=-180/9

11.   x=-20

Answer:

[tex]x = -20[/tex]

Step-by-step explanation:

Starting with:

[tex]3(x + 8) = -3(7 - \frac{1}{4}x)[/tex]

Use distributive property to multply 3 by X + 8

[tex]3x + 24 = -3(7-\frac{1}{4} x)[/tex]

Use distributive property to multiply -3 by 7 - 1/4x

[tex]3x + 24 = -21 - 3(-\frac{1}{4})x[/tex]

Express [tex]-3(\frac{1}{4} )[/tex] as a single fraction.

[tex]3x + 24 = -21 + \frac{- 3(-1)}{4}x[/tex]

Multiply -3 and -1 to get 3

[tex]3x + 24 = -21 + \frac{3}{4}x[/tex]

Subtract [tex]\frac{3}{4} x[/tex] from both sides

[tex]3x + 24 - \frac{3}{4}x= -21[/tex]

Combine 3x and [tex]-\frac{3}{4}x[/tex] to get [tex]\frac{9}{4} x[/tex]

[tex]\frac{9}{4} x + 24 = -21[/tex]

Subtract 24 from both sides

[tex]\frac{9}{4}x = -21 - 24[/tex]

Subtract 24 from -21 to get -45

[tex]\frac{9}{4}x = -45[/tex]

Multiply both sides by [tex]\frac{4}{9}[/tex], the reciprocal of [tex]\frac{9}{4}[/tex]

[tex]x = -45 * (\frac{4}{9})[/tex]

Express it as a single fraction

[tex]x = \frac{-45 * 4}{9}[/tex]

Multiply the top to get -180

[tex]x = \frac{-180}{9}[/tex]

Divide -180 by 9 and get -20

[tex]x = -20[/tex]
