Answer:
y = 2x^2 + 16x + 11
Step-by-step explanation:
2(x + 4)^2 - 21
2(x + 4)(x + 4) - 21
2(x^2 + 8x + 16) - 21
2x^2 + 16x + 32 - 21
2x^2 + 16x + 11
P = 2(L + W)
P = 22
L = 2W + 2
22 = 2(2W + 2 + W)
22 = 2(3W + 2)
22 = 6W + 4
22 - 4 = 6W
18 = 6W
18/6 = W
3 = W.....this is the width
L = 2W + 2
L = 2(3) + 2
L = 6 + 2
L = 8 meters <=== this is the length
Answer:
11
Step-by-step explanation:
Answer:
1a 2dm²= 20000mm² 3dm²=30000mm²
b 18898.8194926 m²
c 0.0054 km²= 540000 dm²
d 1.21931784007 km²
2a 30dm²=3000cm²=300000mm²
b 560cm²=56000mm²
c 7.31cm²=731mm²
Any 3 values above 6 would make this true
