Answer:
x is the missing side (x > 0)
because this is a right triangle, using Pythago theorem, we have:
x² + 4² = 12²
⇔ x² = 12² - 4²
⇔ x² = 128
=> x ≈ 11.3

Answer:
Yes, Sally has enough money to buy 28 cans of soda.
Step-by-step explanation:
Yes, because £10 = 1000p

35 cans < 28 cans
So Sally has enough money for 28 cans.
Answer:
D: 65 km²
Step-by-step explanation:
The formula for area of a hexagon when given the base is
A = (3/2)(√3)b² where b is the length of the base
Here, b is given as 5, plug that in and simplify
A = (3/2)(√3)(5²)
A = (3/2)(√3)(25)
A = (75√3)/2
A ≈ 64.95 ≈ 65
He would walk 2.125 miles or 2 1/8 miles in one hour
