By definition <span>a2=b2+c2</span>, so if b<0 or c<0 or both, b2 and c2 will (always) be positive, and so their sum will always be positive, therefore the hypotenuse, a<span>, will always be positive.

Answer:
2 2/3 yd
Step-by-step explanation:
Let's convert from feet to yards. See how the feet cancel, because feet is in the denominator and the numerator?
8 ft x 1 yd/3 ft = 8/3 yd
As a mixed number:
8/3 = <u>2 2/3 yd of fabric</u>
The 5 is the number of years that the interest rate is fixed (at the initial amount set when you sign the mortgage contract)
The 1 represents the idea that the interest rate will change every year after the initial 5 years are up.
(x,y) = (1, 1.2)
1 = 7(1) - 5(1.2)
1 = 7 - 6
There are many other options though.
Answer:
Step-by-step explanation:
You can't solve for the values of a and b because 6a³b²·2a⁴b³ is an expression, not an equation. However, you can simplify the expression:
6a³b²·2a⁴b³ = 6·2·a³⁺⁴b²⁺³ = 12a⁷b⁵
