Answer:
C
Step-by-step explanation:
The perimeter would be 2*(4(2x+1) + 3(x+4)) because the right side length and the top side length are known. The left side length must equal the right side length and the bottom side length must equal the top side length. So the answer must be:
2*(4(2x+1) + 3(x+4)) = 2*(8x+4+3x+12) = 2*(11x+16) = 22x+32
C. 22x+32

Answer:
5,1
Step-by-step explanation:
7x + 4y = 39
2x + 4y = 14
since, the 4y same for both equation then we can eliminate the 4y by subtracting the two equation
7x + 4y = 39
2x + 4y = 14
---------------- -
5x + 0 = 25
5x = 25
x = 25/5 = 5
then we can input (subtitute) the value of x into the equation, I choose 2x + 4y = 14
2x + 4y = 14
2(5) + 4y = 14
10 + 4y = 14
4y = 14 - 10
4y = 4
y = 4/4 = 1
or if your teacher ask you to use elimination to find the value of x we can write like this
7x + 4y = 39
2x + 4y = 14
make the coeficient of x in both equation same
7x + 4y = 39 (x2)
2x + 4y = 14 (x7)
so
14x + 8y = 78
14x + 28y = 98
--------------------- -
0 - 20y = -20
-20y = -20
y = (-20)/(-20) = 1 (same answer right)
so the correct answe is
(5,1)
Answer:
I'm pretty sure it's 195 times
Step-by-step explanation:
(3, 23, 30-39 (extra for 33), 43, 53, 63, 73, 83, 93) x 5 = 95
95 + 100 (from 300's) = 195
