Aas is not d triangle buddy
Answer:
Roots are [4, -14}.
Step-by-step explanation:
1/2 (x+5)^2 + 2 = 42.5
Work out the square of the parentheses:
1/2 ( x^2 + 10x + 25) + 2 = 42.5
Multiply the parentheses by 1/2:
1/2 x^2 + 5x + 12.5 + 2 = 42.5
Subtract 42.5 from both sides of the equation:
1 /2x^2 + 5x +14.5 - 42.5 = 0
Simplify:
1/2 x^2 + 5x - 28 = 0
Multiply through by 2 to get rid of the 1/2:
x^2 + 10x - 56 = 0
Factor:-
(x + 14)(x - 4) = 0
Either x + 14 = 0 giving x = -14.
or x - 4 = 0 giving x = 4.
I can't answer the last 2 but i can help your with the distributive property the answer to the first one is 66+6x because you distribute the 60 to each thing inside the parentheses 6×11=66 and six times X is 6X. The answer to the second one is 8x+56 because you distribute eight to x which is 8X and 8 times 7 which is 56

Answer:
He hiked 9 1/8 miles
Step-by-step explanation:
First make the fractions like terms
Multiply 4 1/2 by 4/4 to get 4 4/8
Then add the fractions to get 9/8
9/8 is an improper fraction, make it 1 1/8
then add all the whole numbers 4+4+1=9
add the fraction 1/8 to 9= 9 1/8
