Answer: Small number = 15.
Larger number = 20
Step-by-step explanation:
Let the smaller number be x.
The larger of two numbers is five more than the smaller. Thus, the larger number is x+5.
Twice the larger is twenty less than four times the smaller. This can.be written as:
2(x + 5) = 4x - 20
2x + 10 = 4x - 20
2x - 4x = -20 - 10
-2x = -30
x = 30/2
x = 15
The smaller number is 15
Larger number = x + 5 = 15 + 5 = 20
Step-by-step explanation:
<u>Step 1: Add 2cos(x) to both sides</u>


<u>Step 2: Subtract 9 from both sides</u>


<u>Step 3: Divide both sides by 9</u>


<u>Step 4: Find x</u>


Answer: 
I think it would be 90 because every triangle equals 180 and since it’s a right angel that’s 90 degrees for the square and 90+90=180
Answer:
18
Step-by-step explanation:
f(x)=2x(2+1)
f(3)=2(3)(2+1)
=6(2+1)
=12+6
=18
