90 degrees exactly. It is four 90 degree angles
Answer:
1050, 1200, 2550 and 5100.
Step-by-step explanation:
If the first number is x then the second is x + 1/7x.
The third = x + x + 1/7x + 300 and the fourth = x + x + 1/7x + x + x + 1/7x+ 300 + 300.
So our equation is:-
8x + 4 * 1/7x + 900 = 9900
60/7 = 9000
60x = 7*9000
x = 1050.
Therefore the 4 numbers are 1050, *1/7*1050 = 1200, 2550 and 5100.
4^2+3(4)=28 hope this helps
Answer:
Step-by-step explanation:
Okay so the 4(2t +2) and 4t + 8 + 4t go under 8t + 8, because when you distribute and add like terms, you get 8t+ 8 for both
(8*t)+(8*8) and 8t + 64 go under 8(t+8) because similar to the other, when you distribute and add like terms you get 8(t+8) for both
The last two options 8t+16 and (8+t) +(8+8) go under neither because when distributed and added, they don't match up to either or
Hope that helps!
Answer:
f-1(x) = +- sqrt(x + 6)
Step-by-step explanation:
f(x) = x^2 - 6
y = x^2 - 6
x = y^2 - 6
x + 6 = y^2
y = +- sqrt(x + 6)
f-1(x) = +- sqrt(x + 6)
