=>

Step-by-step explanation:
We will cross Multiply the digits
=>20 \div 22 = x \div 20
=>We'll cross Multiply
=>

Answer:
20. 
22. 
24. 
Step-by-step explanation:
20. 
The GCF is x, so you group it out of the equation first.

Then, you find 2 numbers that will equal to 2 when you add them and will equal to -48 when you multiply them.

The two numbers would be -6 and 8. You then differentiate the squares.

22. 
The GCF is 2, so you must group it out.

Find the two numbers that will equal to 5 when you add them and will equal to 4 when you multiply them.

The two numbers would be 1 and 4. Finally, differentiate the squares.

24. 
The GCF is 5m, so you must group it out.

Find the two numbers that will equal to 6 when you add them and will equal to -7 when you multiply them.

The two numbers would be -1 and 7. Finally, differentiate the squares.

-3x + y = 1 ............. the general form is y= mx +b .................y = 1 + 3x
...........................
Y = 3x + 1
Answer:
≈ 35.1 ft
Step-by-step explanation:
The model is a right triangle with ladder being the hypotenuse and the angle between the ground and the ladder is 70°
Using the cosine ratio, with l being the length of the ladder.
cos70° =
=
( multiply both sides by l )
l × cos70° = 12 ( divide both sides by cos70° )
l =
≈ 35.1 ( to the nearest tenth )
The ladder is approx 35.1 ft long
