Answer:
4x + 14
Step-by-step explanation:
From the question,
L =(x + 8)
W =(x -1)
Perimeter of a rectangle
= 2(L + B)
P = 2( x+8 + x-1)
Using distributive property
We have
2xx +2x8 + 2xx -2x1
2x + 16 +2x -2
2x + 2x +16 -2
4x + 14
Answer:
Step-by-step explanation:
Yes it is correct
You must first attach the problems with your question.
<span>1 x + 1 y = 7 .............1
Total value
15 x + 28 y = 131 .............2
Eliminate y
multiply (1)by -28
Multiply (2) by 1
-28 x -28 y = -196
15 x + 28 y = 131
Add the two equations
-13 x = -65
/ -13
x = 5
plug value of x in (1)
1 x + 1 y = 7
5 + y = 7
y = 7 -5
y = 2
y = 2
x= 5 plain shirts
y= 2 fancy shirts </span>
STEP-BY-STEP SOLUTION:
( x + 4 )^2 + y^2 = 22
x^2 + 2 × x × 4 + 4^2 + y^2 = 22
x^2 + 8x + 16 + y^2 = 22
y^2 = 22 - x^2 - 8x - 16
y^2 = - x^2 - 8x + 6
FINAL ANSWER:
Therefore, the answer is:
D. y^2 = - x^2 - 8x + 6
