Answer:

Yes

Step-by-step explanation:

We can see step by step how to solve for x, and get 11.5:

2x+9=32

Subtrract the 9 from both sides. You should always try to get the number on one side, and the variable on the other:

2x+9-9=32-9

=

2x=23

In the end, once the number values are on one side, and the variable value on the other, you want you varaible to be 1.

When I mean 1, I mean you want 1x, or just x.

Here we see 2x=23, meaning we need to divide both sides by 2, to get 1x:

2x/2=23/2

=

x=11.5

So x equals 11.5, and you were correct.

Hope this helps!

Given the length of three sides of a triangle, which is a right triangle?
navik [9.2K]
Pythagoras, cool.
30^2 is 900
15^2 is 225
26^2 is 676
676+225 isn't 900 so it isn't A.

10^2=100
26^2=676
24^2=576
100+576=676 so B is a right angled triangle. 

Hope this helps :)

The rectangular ground floor of a building has a perimeter of 780 ft. The length is 200 ft more than the width. Find the length
ivolga24 [154]

Answer:

L = 295ft

W = 95ft

Step-by-step explanation:

Perimeter of a rectangle = 2(L+W)

If the length is 200 ft more than the width, then:

L = 200+W

Substitute

P = 2(200+W+W)

780 = 2(200+2W)

780 = 400+4W

4W = 780-400

4w = 380

W = 380/4

W = 95ft

Since L = 200+w

L = 200+95

L = 295ft
