Answer:

41 units

Step-by-step explanation:

Pythagorean's  theorem,

Hypotenuse² = base² + adjacent²

Diagonal² = length² + width²

                 = 40² + 9²

                 = 1600 + 81 = 1681

Diagonal = √1681 = 41 units

Solve the equation 5(x-2)=7(x+4) for x
Sphinxa [80]

Answer:

\boxed{\bold{x=-19}}

Step By Step Explanation:

Expand \bold{5\left(x-2\right): \ 5x-10}

Expand \bold{7\left(x+4\right): \ 7x+28}

\bold{5x-10=7x+28}

Add 10 To Both Sides

\bold{5x=7x+38}

Subtract 7x From Both Sides

\bold{5x-7x=7x+38-7x}

Simplify

\bold{-2x=38}

Divide Both Sides By -2

\bold{\frac{-2x}{-2}=\frac{38}{-2}}

Simplify

\bold{x=-19}

Whats the answer of -5+-2p=-9
Nikolay [14]

Answer:

p = 2

Step-by-step explanation:

Step 1: Write equation

-5 + -2p = -9

Step 2: Solve for <em>p</em>

<u>Simplify:</u> -5 - 2p = -9

<u>Add 5 to both sides:</u> -2p = -4

<u>Divide both sides by -2:</u> p = 2

Step 3: Check

<em>Plug in p to verify it's a solution.</em>

-5 - 2(2) = -9

-5 - 4 = -9

-9 = -9

What is the surface area of a circle that has a diameter of 14 inches
Anna007 [38]
The area of any circle is        (pi) · (radius)² .

The radius is 1/2 of the diameter.

For your circle, the radius is 1/2 of 14 inches  =  7 inches,
and the area is

                            (pi) · (7 inches)²

                         = (pi) · (49 square inches)

                         =      153.9 square inches  (rounded)
