Answer:
C.
Step-by-step explanation:
Measure of arcURN = 270°
In radians:
270° = 270π/180
270° = 3π/2
Now
Area of sector = 1/2r²∅
= 1/2(10)²(3π/2)
= 50(3π/2)
= 75π
The answer is if 5(3x - 7 ) = 20 than 6x - 8 is 2(3x - 4) You get this answer when you factor it.
rewrite the equation set = to 0.
x^2 + 5x - 8 = 0
The quadratic will not factor so you have to use the quadratic formula.
x = (-b + - sqrt(b^2 - 4ac))/2a
x = (5 + - sqrt(25 - 4* 1* -8))/2
x = (5 + - sqrt 57)/2
The x2is not the same as 2x. It is x^2. X tot he second power which makes the problem a quadratic equation. You cannot combine the terms x^2 and -5x because they so not have the same power.
Answer:
126?? i think
Step-by-step explanation:
A triangle always ahs a total of 180 degrees, so I added 24+28+6= 54, then subtracted it by 180 and got 126
(Dont fully trust me, im not an expert in geometry :P)
B, 4x(2x2 + 3x)
divide both sides by 4 and you will get 2x2 + 3x to be the most factored form
