Sorry inputed wrong in calculator first time
Hi there!
Let the first number be represented by X.
The second number (which is 2 more than four times the other), can be represented by 4X + 2.
We can now find the sum of this expression.
X + 4X + 2
Collect terms
5X + 2
The sum of the numbers is 18. Therefore we can set up the following equation.
5X + 2 = 18
Subtract 2.
5X = 16
Divide both sides by 5.
X = 16/5 = 3 1/5.
Therefore, the first number is 3 1/5. To find the second number we must plug in X = 3 1/5 into the expression 4X + 2
4 * (3 1/5) + 2 = 12 4/5 + 2 = 14 4/5
The two numbers are

~ Hope this helps you!
You answer is C because 7-(-2) is 9 and then u just had an X at the end .
Hope this helps:)

Answer:
Step-by-step explanation:
Pretty Tall.
Tan(72) = opposite / adjacent
The opposite is the height of the building
The adjacent = 100
Tan 72 = 3.077
Tan (72) = opposite / 100
3.077 = opposite / 100 Multiply by 100
3.077 * 100 = opposite
opposite = 307.7
opposite rounded = 308
