Answer:
A, C, and E good luck
Step-by-step explanation:
Note: "total" is from adding the first and last columns (middle column should be provided because it is a rate which cannot be added).
Amount x Cost = Amount x Cost
Cranberry: q $6.30 $6.30q
Apple: <u> 4 </u> <u>$3.60</u> <u> $3.60(4) = $14.40</u>
Total: 4 + q $4.50 = $6.30q + $14.40
$4.50(4 + q) = $6.30q + $14.40
$18.00 + $4.50q = $6.30q + $14.40
$3.60 = $1.80q
2 = q
Since you didn't provide the equation options, hopefully you can use the solution to help you decide which option to choose.
Answer:
L=10.326cm
P=31.30cm
Step-by-step explanation:
A=55=L*W
L=5+W
A = (5+W)(W) = 55
55=W^2 + 5W
0 = W^2 + 5W - 55
use quadratic formula
W = [-5 (+/-) sqrt(25-4(-55))]/2
W= 5.326 cm or W=-20.65, so W=5.326cm
L=5+5.326
=10.326cm
P=2W+2L
P=2(5.326) + 2(10.326)
=31.30 centimeters
Answer: -3n-2.
Because for the first term, for example, plug in 1, you'll get -3(1)-2=-3-2=-5, which is the first one. Try it with all terms.
Answer:
18 sides
Step-by-step explanation:
Each exterior angle of a regular polygon = 20 deg. So the polygon has 360/20 = 18 sides
