Using the formulas to find its length =
P= 2 ( l + w )
d= w² + l²
There are 2 solutions for,
l = P / 4 + 1 / 4 √8d² - p²
= 39.2 / 4 + 1 / 4 × √8 × 14² - 39²
= 11. 2 km answer.
Using the formula to find its width =
w = p / 2 - l
= 39.2 / 2 - 11.2
= 8.4 km answer.
≈ the length of a rectangle is 11.2 km and the width is 8.4 km
Answer:
b
Step-by-step explanation:
Answer:
No.
Step-by-step explanation:
Because perpendicular means negative reciprocal of the slope. So 4 and -1/4 are perpendicular.
J = jeans. S = shirts.
4s x 4j= 16
Here is another way to figure it out.
Lets say we have four shirts, A, B, C, D.
And four pairs of jeans, E, F,G,H.
A & E + A&F + A & G + A &H.
B&E+B&F+B&G+B&H
C & E + C&F + C&G+ C&H
D& E + D&F + D&G+ D&H
All of these pairs equals 16 total pairs.
I hope this helps!
I'll offer you a deal in return for your 5 points: I'll solve it . . . . You check it.
<u>-1/2x - 7 = -11</u>
Add 7 to each side: -1/2 x = -4
Multiply each side by 2 : - x = -8
Multiply each side by -1 : <em> x = 8</em>
Take it Allalala !
