We have the expression 2x + 3y + 2(x - y) - 3x.
And we need to simplify it.

We can start with distributive property. This states that a(b + c) = ab + ac

2x + 3y + 2(x - y) - 3x becomes 2x + 3y + 2x - 2y - 3x

Then combine like terms. This means if we have two terms that have the same variable and exponent, we can combine them. Which is adding or subtracting.

2x + 3y + 2x - 2y - 3x becomes x + y

So, the answer to this question x + y.

2x + 3y + 2(x - y) - 3x

First you apply the distributive property:

2x +3y + 2(x) - 2(y) - 3x
2x + 3y +2x - 2y - 3x

The you combine like terms:

2x + 2x - 3x +3y - 2y
4x - 3x + y
x (x could also be 1x) + y (y could also be 1y)

The answer is x + y or 1x + 1y

You need to cross a canal and want to determine the distance across the opposite side. Since you're able to take measurements on

MariettaO [177]

Answer:

36.7 ft

Step-by-step explanation:

Measurements for the sides of the canal is given as: 40 ft. and 16 ft.

You solve the above question using Pythagoras Theorem

The distance across the canal is calculated as:

√(40² - 16²)

= √(1344)

= 36.66060556 ft

Approximately = 36.7 ft

Therefore, the distance x across the canal = 36.7 ft

A square pyramid. The square base has side lengths of 6 inches. The 4 triangular sides have a base of 6 inches and height of 9 i

Marrrta [24]

Answer:

The area of the pyramid’s base is 36 in².

The pyramid has 4 lateral faces.

The surface area of each lateral face is 27 in².

Step-by-step explanation:

"<u>Lateral</u>" means side, so the lateral faces are <u>triangles</u>.

The <u>base</u> is the bottom, which is a <u>square</u>.

To calculate the <u>area of the base</u>, use the formula for area of a square.

$A_{base} = s^{2}$

$A_{base} = (6 in)^{2}$

$A_{base} = 36 in^{2}$

To calculate the <u>area of a lateral face</u>, find the area of a triangle.

$A_{lateral} = \frac{bh}{2}$

$A_{lateral} = \frac{(6 in)(9 in)}{2}$

$A_{lateral} = \frac{54 in^{2}}{2}$

$A_{lateral} = 27 in^{2}$

In a pyramid, the number of lateral faces is the same as the number of sides in the base. <u>The square base as 4 sides, so there are 4 lateral faces</u>.
