Length (L): 2w + 3
width (w): w
Perimeter (P) = 2L + 2w
60 = 2(2w + 3) + 2(w)
60 = 4w + 6 + 2w
60 = 6w + 6
54 = 6w
9 = w
Length (L): 2w + 3 = 2(9) + 3 = 18 + 3 = 21
Answer: width = 9 feet, length = 21 feet
Assuming the spaces mean plus (+):
2(3y+5) = 3(5y+13)
6y+10 = 15y+39
10 = 9y+39
9y = -29
Therefore, y = -29/9 or -3.22
Answer:
A. No. B. 3
Step-by-step explanation:
A. The point is (4, 20) plug these into the equation with m being 2,
20=2(4)+8
20=8+8
20=16, this statement is not true, so m can't be 2.
B. 20=4m+8
-8 -8
12=4m divide by 4 on each side,
m=3
0.7 = 0.7000000000000000000000000
Answer:
Step-by-step explanation:
2x+10x=12x
12x=-21
x=-1.75
