I JUST NEED 2. ANSWERED! THIS IS DUE! Solve for x

8_murik_8 [283]

Answer:

x=24

Step-by-step explanation:

Since line A and B are parallel, 3x+7 is equivalent to Angle 6 as they are corresponding angles.

We also know that 4x+5+Angle 6 = 180 as they are a linear pair. We can use substitution and substitute 3x+7 for Angle 6...

4x+5+3x+7=180

7x+12=180

7x=168

x=24

The diagram show a 5cm x 6cm x 7cm cuboid pls help you

kotegsom [21]

Answer:

d ≈ 10.5

Step-by-step explanation:

The formula for the diagonal of a retangular prism (cuboid) is

$d=\sqrt{l^2+w^2+h^2}$

1.) Plug in all the values for l, w, and h

$d=\sqrt{5^2+6^2+7^2}$

2.) simplify by squaring the terms inside the square root

5 * 5 = 25

6 * 6 = 36

7 * 7 = 49

$d=\sqrt{25+36+49}$

3.) Add the terms

$d=\sqrt{110}$

4.) Simplify

$d = 10.488$

5.) Round to one decimal place

d ≈ 10.5
