Answer:
John is 9 and Olivia is 12
Step-by-step explanation:
12+18= 20
36+ (9x8)= 108
Sin (Angle) = Opposite / Hypotenuse
Sin (X) = 8/17
X = Arcsin(8/17)
X = 28.07 degrees.
Answer:
12a+2b
Step-by-step explanation:
1. Expand by distributing terms.
20a-8b-2(4a-5b)20a−8b−2(4a−5b)
2. Expand by distributing terms.
20a-8b-(8a-10b)20a−8b−(8a−10b)
3. Remove parentheses.
20a-8b-8a+10b20a−8b−8a+10b
4.Collect like terms.
(20a-8a)+(-8b+10b)(20a−8a)+(−8b+10b)
5. Simplify.
12a+2b12a+2b
6.Answer
12a+2b
Answer:
Step-by-step explanation:
√x^72 = √(x^36)^2 = x^36
yes it is correct
with parentheses you have to bring EVERYTHING INSIDE THE PARENTHESES to the given power but not if there are no parentheses
