Answer:
Length = 5
Width = 21
Step-by-step explanation:
(x)(x + 16) = 105
x^2 + 16x = 105
x^2 + 16x - 105 = 0
(x - 5) x ( x + 21) = 0
x - 10 = 0
x = 5
x + 21 = 0
x = -21
Now that we have the zeroes.
We have to find the most viable one to put in.
Using -21 would not make sense, so we will use 5.
Plug it in:
x = 5
(5) (5 + 16) = 105
5 ( 21) = 105

PEMDAS:
Equation: 15 + 7 x 4
if there are parenthesis and the equation looks like:
(15 + 7) x 4
the <u>answer is 88</u>.
if there is NOT parenthesis and the equation looks like:
15 + 7 x 4
the <u>answer is 43</u>.
Answer: choice C) 19/60
----------------------------------------------------------------------------------------------------
Explanation:
Add up the minute values: 19+4+37 = 60
We have a total of 60 minutes. Of that total, 19 minutes is dedicated to news.
Divide the two values (19 and 60) to get the fraction 19/60. We can't reduce from here so we leave it like that.
