Answer:
Cool where the rest of the problem
Step-by-step explanation:
To simplify the expression (5x^2 - 21x - 20) / (5x^2 - 16x - 16), we can check if there are terms that are needed to be added or subtracted. In this case, there are none. We just check the factors of each polynomial above and below. The factored equation of the numerator is (x-5)*(x + 4/5) while that below is (x-4)* (x + 4/5). In this case, we cancel <span>(x + 4/5). Hence the answer is (x-5) / (x-4)</span>
Answer:
x = 34.06
Step-by-step explanation:
The sum of angles in the triangle LUV is 180 degrees
Given
∠L=(3x+y)°
∠U=42.6°
∠V=(4x−3y−0.8)°
Since ∠L+∠U + ∠V = 180 degrees
Substitute:
3x+y + 42.6 + 4x - 3y - 0.8 = 180
7x - 2y - 41.8 = 180
7x - 2y = 221.8 ... 1
Since UV = UL, hence the triangle is isosceles and <V = <L
3x+y = 4x-3y - 0.8
-x +4y = -0.8
x - 4y = 0.8 ....2
From 2: x = 0.8+4y
Substitute into 1:
7x - 2y = 221.8
7(0.8+4y) - 2y = 221.8
5.6 + 28y-2y = 221.8
26y = 221.8-5.6
26y = 216.2
y = 8.32
Get x
x = 0.8+4y
x = 0.8+4(8.32)
x = 0.8 + 33.26
x = 34.06
<em>Note that it was assumed that <V = <l since the question is not clear</em>
First Equation
STEP 1: Move the variable to the right side and change its sign
3x=8-y
STEP 2: Divide both sides of the equation by 3
x=8/3 - y/3
STEP 3: Write all numerators above the common denominator
x=8-y/3
THE FINAL ANSWER IS:
x=8-y/3
Second Equation
STEP 1: Move variable to the right side and change its sign
-x= -10+2y
STEP 2: Change the signs on both sides of the equation
x=10-2y
THE FINAL ANSWER IS:
x=10-2y
