Answer:
12 ft
Step-by-step explanation:
The ladder forms a right triangle with the building and the ground, since the ground is perpendicular to the building
Therefore, we can use the Pythagorean theorem:
c2 = a2 + b2
From the information in the problem, c is 20 ft, b is 16 ft, and a is what we solve for:
(20 ft)2 = a2 + (16 ft)2
a = √((20 ft)2 - (16 ft)2) = 12 ft
3.2 gallons
You see what you do is you divide 120 by 37.5 and you will get the number of gallons
Answer:
Hello :)
So here is how you get the simplified form of the given value above.
x/4+y/3
----------
x/3−y/4 What you are going to do is just to cross multiply.
Which will give us the result:
3x + 4y
---------
4x - 3y
Therefore,
3x + 4y
---------
4x - 3y is the simplified form of the given values above.
Hope this answer helps.
Answer:
A
Step-by-step explanation:
If you simplify the equation you are left with 5 = -1, which is an untrue statement. Therefore, no matter what value you use for x you will always be left with 5 = -1.
