Answer:
The sticker is 8 millimeters x 6 millimeters
Step-by-step explanation:
A = Lw = 48
P = 2L + 2w = 28
<u>Perimeter:</u>
2L + 2w = 28
2 (L + w) = 28
L + w = 14
L = 14 - w
<u>Subsitute Into Area:</u>
A = Lw = 48
(14 - w)w = 48
14w - w² = 48
<em>(subtract/add 14w - w² to both sides)</em>
0 = w² - 14w + 48
Solve ^
= 8 and = 6
Typically the length is larger, so our answer is
The sticker is 8 millimeters x 6 millimeters
(hopefully this makes sense, have a nice day!)
Answer:
-7
Step-by-step explanation:
8=r+15
-15 -15
-7=r
check
8=r+15
substitute
8=-7+15
8=8 check
The answer is 2/5 because 100/20 is five and if you add another twenty, you get forty, so it is 2/5.
Answer:
The Answer is: (-6, 11); (3, 5); (15, -3); (-12, 15)
Step-by-step explanation:
f(-6) = -2/3(-6) + 7 = 12/3 + 7 = 4 + 7 = 11
f(3) = -6/3 + 7 = -2 + 7 = 5
f(15) = -30/3 + 7 = -10 + 7 = -3
f(-12) = -2/3(-12) + 7 = 24/3 + 7 = 8 + 7 = 15
To find the -12, you have to solve for x:
-2/3x + 7 = 15
-2/3x = 15 - 7
-2/3x = 8
x = -3/2 * 8 = -24/2 = -12
Then to prove the number, find f(-12) = 15
