5 0

Answer:

The system has no solution because if 0=8, this means this is an empty set. If you get 2 numbers that don't equal each other for an answer then you know there's no solution

I do not understand this at all!

Answer:

∠1 = 51° ∠2 = 39°

Step-by-step explanation:

ok since the picture is a right angle put it equal to 90

like this:

3x + x + 22 =90

4x + 22 = 90

4x = 68

x = 17

now we plug it in:

3(17)= 51°

(17) + 22 = 39°

*a straight line is equal to 180, a right angle is 90

does that make sense?

One positive number is 4 more than twice another. Their product is 198

Answer:

$\large \boxed{\sf \ \ 9 \text{ and } 22 \ \ }$

Step-by-step explanation:

Hello,

We can write that, x being the second number

(4 + 2*x) *x = 198

Let's solve this equation.

$(4+2x)x=198\\\\4x+2x^2=198 \\\\\text{*** subtract 198 from both sides ***}\\\\2x^2+4x-198 = 0\\\\\text{*** The product of the zeroes is -198/2=-99=-11*9 and their sum is -4/2=-2 ***}\\\\2x^2+4x-198=2(x-9)(x+11)=0\\\\x=9 \ \ or \ \ x=-11$
