Answer:

Since all triangle angles add up to 180°, you can set all the angles equal to 180.

(96 + 2x + (x + 12)) = 180

You can now simplify it together

108 + 3x = 180

Now you can isolate x by itself

180 - 108 = 72

72 / 3 = 24

x = 24

What is the perimeter of a rectangle with a length of 15 ft and a width of 32 ft

romanna [79]

Answer:

94 ft

Step-by-step explanation:

A rectangle shares 2 congruent lengths & 2 congruent width sides.

The perimeter is the total measurement of all sides added together. Solve:

2(15) + 2(32) = 30 + 64 = 94

94 ft is your answer.

Answer:

Step-by-step explanation:

So the whole segment TV is made up of TU plus UV. In an equation:

$TV=TU+UV$

We already know that TV is 32 and UV is 20. Substitute:

$32=TU+20$

Subtract 20 from both sides:

$TU=12$

So, the length of TU is 12.

Our answer is A.

And we're done!

$\qquad\qquad\huge\underline{{\sf Answer}}♨$

Let's write the equation of line in slope point form ~

$\qquad \sf \dashrightarrow \:y - y1 = m(x - x1)$

$\qquad \sf \dashrightarrow \:y -2 = 3(x -1)$

$\qquad \sf \dashrightarrow \:y -2 = 3x - 3$

$\qquad \sf \dashrightarrow \:y = 3x -1$

Now, let's use this equation of line to plot two points ~

when x = 0, y = (3 × 0) - 1 = - 1

when x = -1, y = (3 × -1) -1 = -4

Now, plot these points on graph ~

(0 , -1) and (-1, -4)

Solve for x.<br> A) -7<br> C) 6<br> B) 9<br> D) 10

Mekhanik [1.2K]

Answer:

Step-by-step explanation:

The segment BC joining the midpoints of 2 sides of the triangle is

Half the length of the third side, that is

x + 31 = 2(x + 19)

x + 31 = 2x + 38 ( subtract x from both sides )

31 = x + 38 ( subtract 38 from both sides )

- 7 = x → A

Each step in a procedure to solve this equation is shown. Find where the first error occurs. Given: 2(x - 4) = 8x + 16

quester [9]

Answer:

Step-by-step explanation:

It is B because he makes the error of adding 8x to 2x instead of subtracting 8x from 2x.
