A ladder is leaning against the side of a building. The
cupoosta [38]

Answer:

16 ft

Step-by-step explanation:

Based on the situation above, it forms into a right triangle. Therefore we can apply the Pythagorean Theorem. We will use the formula below:

c = √( a² + b²)

In the problem above, the ladder acts as the hypotenuse denoted by c. It has a length of 20 ft. While the base denoted by b is 12 ft. Therefore, we need to solve for a. We will derive the formula above.

c² = a² + b²

a² = c² - b²

a = √( c² - b² )

a = √( 20² - 12² )

a = 16

The unit is in ft.

Correct me if I'm wrong. I hope it helps.

MULTIPLE CHOICE<br> What is LM?<br> 3x + 5<br> 4x + 7<br> LN = 33 cm
FromTheMoon [43]

Answer:

C. 14

Step-by-step explanation:

Add LM and MN

(3x + 5) + (4x + 7)

(4x + 3x) + (5 + 7)

7x + 12

As we know the total is 33

So,

7x + 12 = 33

Subtract 12 from 33, which gives me 21

Now,

7x = 21

To make x alone, divide both sides by 7, and then we will get x = 3

If x = 3

LM = 3x + 5

= (3*3) + 5

= 9 + 5

= 14

Find the product.<br> (2x+3)(2x-3)<br> A. 4x2 - 9<br> B. 4x2 +9<br> C. 4x2 –5x+9<br> D. 4x2 - 5x-9
Mademuasel [1]

Answer:

A. 4x^2 - 9

Step-by-step explanation:

2x * 2x = <u>4x^2</u>

2x * -3 = <u>-6x</u>

3 * 2x = 6x

-3 * 3 = -9

-6x + 6x  = 0, so we're left with 4x^2 - 9
