X = 2 cm

You need to use the Pythagorean theorem starting with the triangle on the far left and progressively moving to the right. (Comment if you want further explanation)

Answer:

2 cm

Step-by-step explanation:

First you use Pythagorean theorem in solving the triangle closest to the bottom. You would get the square root of two. Then you use Pythagorean theorem again on the second triangle and receive the answer of the square root of three you do the Pythagorean theorem again and receive the answer of the square root of four. Simplify that and get 2 cm.

(7 + X) x 8 - 4 x X = 56
devlian [24]

Answer:

12 1/4

Step-by-step explanation:

(7 + X) × 8 - 4 × X = 56

7 + X × 8 - 4 × X = 56

7 + 8X - 4 × X = 56

7 + 8X - 4X = 56

7 + 4X = 56

4X = 56 - 7

X = 49/4

X = 12 1/4

Which point lies on the line defined by 2x – y = 7?
Eduardwww [97]
So lets just assume that y = 1 since 2x is most likely an even number.
Then we can say that 2x = 8
8 divided by 2 is 4
so a point on this line could be (4,1)
Hope this helped

4(a + 2) = 14 – 2(3 – 2a)<br><br> –2<br><br><br> –1<br><br><br> no solution<br><br> all real numbers
Ray Of Light [21]

All real numbers.

\boxed{TRUE}

Step-by-step explanation:

Distributive property: a(b+c)=ab+ac

Expand: 4(a+2)=4a+8

Expand again: 14-2(3-2a)=4a+8

4a+8=4a+8

You subtract by 8 from both sides of an equation.

4a+8-8=4a+8-8

Simplify.

4a=4a

Then, subtract by 4a from both sides of an equation.

4a-4a=4a-4a

Finally, simplify.

4a-4a=0

0=0

True

All real numbers is the final answer.

Hope this helps you!

Have a nice day! :)
