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:
B. Subtraction property of equality
Step-by-step explanation:
If you subtract angle 3 from both sides, then angle two and angle four must be equal. The property you would be using is the subtraction property of equality.
Cross multiply to solve
(-3r)(4)=(-27)(2)
Multiply on both sides
-12r=-54
Divide both sides by -12
r=4.5
Final answer: r=4.5
Check:
-3(4.5)= -13.5
-13.5/2= -6.75
-27/4=-6.75
