7.2(2.8r-4.5s)+9.34r -1.25s
=20.16r - 32.4 +9.34r -1.25s
=29.5r - 33.65s
So the answer is A
hope I can help u
Answer:
The width of the rectangle is 2.5 feet
Step-by-step explanation:
Here, we want to calculate the width of the rectangle given its length
Let the area = perimeter = x
Mathematically;
area of rectangle = L * B = 10B
The perimeter of the rectangle = 2(L + B)
Also;
x = 10B
Let’s equate this to the perimeter
x = 10B = 2(L + B)
10B = 2(10 + B)
10B = 20 + 2B
10B -2B = 20
8B = 20
B = 20/8
B = 5/2
B = 2.5
Answer:
2/3×3/8 < 2/3
Step-by-step explanation:
2/3×3/8 =1/4=0.25
2/3=0.666...
2/3 is larger
Answer:
20
Step-by-step explanation:
First step is finding an angle in the rightmost triangle (angle K)
Using TOA we have
Tan(x)=4/8
x=26.565
which means that 90-26.565= 63.4349 will give us angle K in regards to the left triangle
Using this we can solve for JM
Tan(63.4349)=x/8
8tan(63.4349=x
x=16
So if JM = 16
and LM=4
take their sum to find JL
16+4=20
A cause you just gotta think about it and realize you got it
