Answer:
14
Step-by-step explanation:
The applicable rule of exponents is ...
(a^b)(a^c) = a^(b+c)
__
You have ...
(x^3)(x^a) = x^17
x^(3+a) = x^17
Equating exponents, we get ...
3 +a = 17
a = 14
The missing exponent is 14.
Answer:
Step-by-step explanation:
25+105+x=180 degree(being sum of the interior angles of a triangle)
130+x=180
x=180-130
x=50 degree
Answer:
5 sq. ft.
Step-by-step explanation:
To find the area of a rectangle, use this formula: A = lw.
Because you know two side lengths of the window, you can just plug in the numbers to the formula.
But not yet! You need to convert the given lengths into feet first.
You know that there are 12 inches in 1 foot.
So:
24 inches ÷ 12 inches/foot = 2 feet
30 inches ÷ 12 inches/foot = 2.5 feet
Alright, now you can plug in these lengths into the formula.
A = (2) (2.5) = 5 sq. ft.
The question asks you to round, but there is nothing to round, so you are done here.
