If you would like to write a * b + c in simplest form, you can do this using the following steps:
a = x + 1
b = x^2 + 2x - 1
c = 2x
a * b + c = (x + 1) * (x^2 + 2x - 1) + 2x = x^3 + 2x^2 - x + x^2 + 2x - 1 + 2x = x^3 + 3x^2 + 3x - 1
The correct result would be x^3 + 3x^2 + 3x - 1.
Answer:
No Real Solutions.
Step-by-step explanation:
√(x-5)=8√(x-2)
Square on both sides,
(√(x-5))^2=(8√(x-2))^2
or,(x-5)=64(x-2)
or,x-5=64x-128
or,-5+128=64x-x
or,123/63=x
Therefore, x=41/21
If you plug x=41/21 in √(x-5)=8√(x-2) you do not get equals, so the problem has no real solutions.
Answer:
5/2
Step-by-step explanation:
duh
This is pretty much 75% of 55.5 which is 41.625. Rounding that up would make $41.63.
C=90°
Since the triangles are similar, the angles will be the same. A corresponds with D and equals 75° and B corresponds with E and equals 15°, so C and F must be 90°, since the angles in a triangle add up to 180°.
Hope this helps :)
