Simplify by distributive property and combine like terms 3(4x)-3+4(6x+1) and -7(3x)+2(3x-2)​

triangle abc is reflected on the line x=-6.5 then reflected again on the x axis

step-by-step explanation:

the anwser is d) 75°

step-by-step explanation:

i use my brain for prombles like this maybe you could try it

step-by-step explanation:

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
