Answer:
see explanation
Step-by-step explanation:
(a)
1.2² = 1.2 × 1.2 = 1.44
(b)
2³ + 17 - 3 × 4 ← evaluate exponent and multiplication before adding/subtracting
= 8 + 17 - 12 = 25 - 12 = 13
(c)
9² ÷ 3³ ← evaluate exponents before dividing
= 81 ÷ 27 = 3
Answer:
72
Step-by-step explanation:
Given that 2x + 3y = 12 , then
(2x + 3y)² = 12² = 144 ← distribute left side using FOIL
4x² + 12xy + 9y² = 144 ( subtract 12xy from both sides )
4x² + 9y² = 144 - 12xy = 144 - 12(6) = 144 - 72 = 72
Answer:
$13
Step-by-step explanation:
Let's set up a ratio...
2:3.25
8:x
We know 2*4 is 8 so we need to multiply 3.25 by 4 to get x...
3.25*4=$13
Step-by-step explanation:
Demand for Goods and Services. Economists use the term demand to refer to the amount of some good or service consumers are willing and able to purchase at each price. The total number of units purchased at that price is called the quantity demanded.
