You can set this up as 2 fractions equal to each other, like ratios.
18/11=108/x
Cross multiply and you get 18x=1,188
Now divide both sides by 18 and get x.
x=66.
If the height of the building is 108ft, the width is 66ft.
It's not possible, because the sum of the lenghts of every two sides of a triangle has to be greater than the length of the third one. It this case that condition isn't met:
Answer:
Integers and polynomials are both <u>closed </u>under addition, subtraction, and multiplication; however, operations on polynomials <u>can sometimes be open </u>while operations on integers <u>produce irrational results
</u>.
Step-by-step explanation:
Closed means that addition, subtraction, and multiplication of integers gives as result a new integer; and addition, subtraction, and multiplication of polynomials gives as result a new polynomial.
Operations on polynomials can sometimes be open, like in division.
Operations on integers can produce irrational results
, for example, dividing 11 by 9.
Answer:
x = 15
Step-by-step explanation:
(2x + 20) + 130 = 180
2x + 150 = 180
- 150 - 150
2x = 30
/2 /2
x = 15
