Diagonals of a rectangle are congruent.
18x - 28 = x + 380
Solving for x, I get 17.
So, x = 17.
PR = 18x - 28
PR = 18(17) - 28
PR = 278
QS = x + 380
QS = 17 + 380
QS = 397
Answer:
28.26ft
Step-by-step explanation:
A=πr^2
π*3^2=28.27433
28.26
Answer:
D
Step-by-step explanation:
The formula for C is
C=2πr (using 3.14 as pi)
so C=2(3.14)(45)
so C=90(3.14)
so C≈282.6 or D
Well if it’s a square all sides are equal, so all sides are 7ft.
Perimeter=
7+7+7+7=28ft
Or
7•4=28
Hope this helps!!!
Answer:
The system of equations is
and
Fred's age is 36 years old and Nathan's age is 9 years old
Step-by-step explanation:
Let
f -----> Fred's age
n ----> Nathan's age
we know that
-----> equation A
----> equation B
equate the equations and solve for n
Find the value of f
therefore
Fred's age is 36 years old and Nathan's age is 9 years old
