The answer to x is 7 because 4 times 6 is 24 and 7 times 6 is 42
40 pints are in 5 gallons
Product of complex numbers (-3i +4) and (3i +4)
(x - y)(x + y) = x² - y²
(-3i +4)(3i +4) = (4 -3i )(4 + 3i) = 4² - (3i)² = 16 - 9*(-1)=16 + 9 = 25
Answer:
<h2>120 Pennies</h2>
Step-by-step explanation:
First, we need to find 80% of 400
400 x 0.8 = 320
Now 50% of 400 is 200
320 - 200 = 120
