Answer:

Step-by-step explanation:
So we have the expression:

To multiply, distribute the left to the terms on the right:

Distribute:

Combine like terms:

Simplify:

Therefore:

X = 60 degrees.
A triangle is 180 degrees one side is 30 degrees, and another is 90(right angle)
180 - 30 - 90 = 60

is given
here ,
or,

or,

or,7x²+3x-4=-4
or,7x²+3x=0
or,x(7x+3)=0
Either,x=0| Or,7x+3=0
|or,7x=-3
|or,x=

So , the solution set is S={0,-

Its would be orange because only two people liked it out of all the kids asked.
You would do ten times fifty. which would be 500
