Answer:

Step-by-step explanation:

First we will solve the Left Hand Side:

(x-2)(-5x²+x)

Multiply the terms:

= -5x³+x²+10x²-2x

Solve the like terms

= -5x³+11x²-2x

Now we will solve the Right Hand Side:

(x)(-5x²)+(x)(x)+(-2)(-5x²)+(-2)(x)

Multiply the terms:

-5x³+x²+10x²-2x

Solve the like terms:

-5x³+11x²-2x

Hence it is proved that L.H.S = R.H.S....

Answer:

Yes because 5^2 + 12^2 = 13^2

Step-by-step explanation:

We can check using the Pythagorean theorem

a^2 + b^2 = c^2

5^2 + 12^2 = 13^2

1) What is the surface area?<br> 1 ft<br> 8 ft<br> 4 ft
WITCHER [35]

Answer:

88 ft^2

Step-by-step explanation:

For a rectangular prism with dimensions 1 ft by 8 ft by 4 ft, there are two opposite faces with dimensions

<em>1 ft by 8 ft, </em>

two opposite faces with dimensions

<em>1 ft by 4 ft, </em>

and two opposite faces with dimensions

<em>4 ft by 8 ft.</em>

We find their area and add them.

SA = 2 * 1 ft * 8 ft + 2 * 1 ft * 4 ft + 2 * 4 ft * 8 ft

SA = 16 ft^2 + 8 ft^2 + 64 ft^2

SA = 88 ft^2

Pythagorean Theorem Word
diamong [38]

Answer:

40 miles

Step-by-step explanation:

In the attached diagram, Point A is the starting point and C is the end point. We want to determine the distance from A to C.

The path driven forms a right triangle in which AC is the hypotenuse.

We therefore use the<u> Pythagorean Theorem</u> to solve for the AC.

Pythagorean Theorem: Hypotenuse^2=Opposite^2+Adjacent^2

|AC|^2=32^2+24^2\\|AC|^2=1600\\|AC|=\sqrt{1600}\\ |AC|=40$ miles

The  straight  line distance from the starting point is 40 miles.
