by law of exponent we obtain:

simplify square:

when x is -1:

rewrite ⅕ in exponent notation:

use law of exponent which yields:

when x is 3:

by law of exponent we obtain:

simplify square which yields:

Answer:
answer is 33.5
Step-by-step explanation:
1/2m-3/4=16
1/2m=16+3/4
1/2m=64+3/4
1/2m=67/4
m=67/4×2
m=33.5
Answer:

Step-by-step explanation:
Substitute 1/2 wherever you see x

= -1/3 +5
= -1+15/3
=14/3
Answer:
7.8 cm and 25.3 cm
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
?² + 7² = 10.5²
?² + 49 = 110.25 ( subtract 49 from both sides )
?² = 61.25 ( take the square root of both sides )
? =
≈ 7.8 cm ( to 1 dec. place )
Then
P = 10.5 + 7 + 7.8 = 25.3 cm
