32 divided bye 4 well = -8
What is the question asking? i dont know if you want to find the angle (which is 90 degrees) or if you ant to find 24^2 (which is 576) or if you want the square route (which is 4.89897948557 or simplified to the nearest tenth its 4.9)
Answer:
((1+2)*3+4)*5
Step-by-step explanation:
1+2×3+4×5=65
-----------------------
- ((1+2)×3+4)×5=
- (3×3 + 4)×5 =
- (9 + 4)×5 =
- 13×5 = 65
Answer:
Step-by-step explanation:
You can create a ratio from the provided recipe,
for every 6 cups of brown sugar you need 9 cups of white sugar so it would be 6:9
?:24
24/9=2.6
6x2.6=15.6
so for 24 cups of white sugar you would need about 16 cups of brown sugar.

Answer:
the one real zero is in the interval (-1, 0)
Step-by-step explanation:
Descartes' rule of signs tells you there are 0 or 2 positive real zeros. Changing the signs of the odd-degree terms and applying that rule again tells you there is one negative real zero. At the same time, those coefficients (-3, -5, -5, +7) have a negative sum, so you know ...
f(-1) = -6
f(0) = +7
so there is a zero in the interval (-1, 0).
__
You can try a few values between x=0 and x=10 to see what the function does in that part of the graph. You find ...
f(1) = 10
f(2) = 21
f(3) = 58
So, it is safe to conclude that there are no real zeros for x > 0.
The only real zero of f(x) is in the interval (-1, 0).
