Area=length times width
area=28
length=7
28=7 times width
divide both sides by 7
4=width
the width is 4 miles
and perimiter is 22mi
Answer: -4
Work: So, to get -4, we need to simplify the equation. If you see any equation with +(- that's subtraction. So, with the rule, this equation is basically 8-12, and that's -4.
Answer: 34
Step-by-step explanation:
<u>Given expression</u>
[3 - (3 · 3) + 33 ÷ 3] × 4 · 5 / 10 - 2 · 3
<u>Simplify by parentheses in the bracket</u>
=[3 - 9 + 33 ÷ 3] × 4 · 5 / 10 - 2 · 3
<u>Simplify by multiplication</u>
=[3 - 9 + 33 ÷ 3] × 20 / 10 - 6
<u>Simplify by division</u>
=[3 - 9 + 11] × 10 - 6
<u>Simplify by bracket (addition/subtraction)</u>
=[-6 + 11] × 10 - 6
=[4] × 10 - 6
<u>Simplify by multiplication</u>
=40 - 6
<u>Simplify by subtraction</u>
=

Answer:
96 sqrt(210)
Step-by-step explanation:
6√3 • 8√14 • √10 • √2
We multiply what is outside the square roots with what is outside the square roots and what is inside the square roots with what is inside the square roots
6*8 = 48
3*14*10*2 = 840
6√3 • 8√14 • √10 • √2
48 sqrt(840)
48 sqrt( 4*210)
sqrt(a*b) = sqrt(a) sqrt(b)
48 sqrt(4) sqrt(210)
48 *2 sqrt(210)
96 sqrt(210)
210 is 3*7 *5*2 which are all primes, so we cannot simplify the sqrt (210)
$280 is her goal. Good luck and have a great day!
