Answer: -16n-41
Step-by-step explanation:
first, distribute 2 through the parentheses:
<u>2(-n-3)</u>-7(5+2n) = <u>-2n-6</u>-7(5+2n)
second, distribute 7 through the parenthesis:
-2n-6<u>-7(5+2n) </u>= -2n-6<u>-35-14n</u>
Collect like terms:
<u>-2n</u>-6-35 and <u>-16n</u>-6-35
Calculate the difference:
-2n<u>-6-35</u>-14n = -16n-<u>41</u>
SOLUTION:
<u>-16n-41</u>
Answer:
450 feet at ground level
Step-by-step explanation:
The width of the bridge at ground level will be where the function intercepts the x-axis also known as the roots or zeros of the function. They are found using the zero product property to set each factor equal to 0.
This means (x-225) = 0 and (x + 225) = 0. So x = -225, 225.
This means the width is the absolute value of |-225| + 225 since distance cannot be negative. This makes it 450 feet.
