Answer:
P = 2x + 2y + 14
Step-by-step explanation:
Answer:
P = 2x + 2y + 14
Step-by-step explanation:
Length (L) = x + 8 units
Width (W) = y - 1 units
Perimeter (P) = 2L + 2W
P = 2(x + 8) + 2(y - 1)
P = 2x + 16 + 2y - 2
P = 2x + 2y + 16 - 2
P = 2x +2y + 14

Step-by-step explanation:
x^2+20=2x move 2x to the left
x^2-2x+20=0
Quadratic formula =
x=1± i√19
area of a triangle = 1/2 base x height
56.4 = 1/2 x 12 x height
56.4 = 6 x height
height = 56.4 /6 = 9.4cm
Answer:
The answer is 687
Step-by-step explanation:
You need to add them all up and then divide by the number of rates which is 5
1.700+650+680+710+695=3435
2.3435/5=687

Answer:
B. 4.29
Step-by-step explanation:
Answer:
Width (length of shorter side) = 3.5 cm.
Step-by-step explanation:
L = 8.5 cm
perimeter, P = 24 cm
2(L+W) = 24
substitute L = 8.5
2(8.5+W) = 24
8.5 + W = 24/2 = 12
W = 12 - 8.5 = 3.5 cm
