Answer:

x=20; vertical angles theorem

Step-by-step explanation:

hi! we can use the vertical angles theorem for this. vertical angles are congruent to each other, meaning they are the same amount of degrees. so, we can set 2x+10 and 50 equal to each other.

2x+10=50

2x=40

x=20

x=20 because of the vertical angles theorem.

So I have the following integral (Please note that the number below is -2 but for some reason LateX did not accept a negative nu

kramer

$f(x)=4x^3-4x+1\\ F(x)=x^4-\frac{x^2}{2}+x\\ \int_{-2}^{2} f(x)=F(2)-F(-2) \implies\\ (2)^4-\frac{2^2}{2}+2)-((-2)^2-\frac{(-2)^2}{2}-2)= \\ 16-2+2-(16-2-2)=16-(16-4)=4$

I've done this a million times and I'm still getting 4 instead of 32. Are you sure you posted the coefficients?

How do I solve this equation 2.4c-2=0.4(1+6c) I end up with -2= 0.4

ratelena [41]

2.4c-2=0.4+2.4c
subtract 2.4c from both sides
-2= 0.4

Answer:

There is a circle with a diameter[d] of 2.

Step-by-step explanation:

the Radius=diameter /2=2/2=1 units

now

circumference=2πr=2×π×1=6.29=6 units

area=πr²=3.14 unit²
