Answer:
Step-by-step explanation:
we have
<em>The equation of the first line</em>
------> equation A
<em>The equation of the second line</em>
------> equation B
Solve the system of equations by elimination
Multiply equation A by -4 both sides
--------> equation C
Adds equation B and equation C
<em>Find the value of x</em>
substitute the value of y
Multiply by 3 both sides
therefore
The solution to the system of equations is the point
Answer:
The answer would be 26
Step-by-step explanation:
First I divided the shape to make a rectangle and a right angle triangle, then i calculated the shape of the rectangle which came out to be 20. After that I calculated the area of the right angle triangle which is 6. So The answer would be 6 + 20 = 26
Foil
15+6i-20i-8i^2
-8i^2=8
15+8+6i-20i
23-14i
All -1.8
In addition and subtraction the order of the numbers does not matter, so the result will always remain the same
