Answer:
x = 2
Step-by-step explanation by completing the square:
Solve for x:
x^2 - 4 x + 4 = 0
Write the left hand side as a square:
(x - 2)^2 = 0
Take the square root of both sides:
x - 2 = 0
Add 2 to both sides:
Answer: x = 2
Answer:
{5}
Step-by-step explanation:
6(5)-4 = 2(5)+16
30-4 = 10+16
26 = 26
Answer:
B) 25 units
Step-by-step explanation:
Do the Pythagorean theorum. 7^2+24^2=625
sqrt of 625=25
Answer:
5 foot rise over 2 foot run
Step-by-step explanation:
when u turn the fractions in to decimals that helps... 3/2 = 1 1/2= 1.5 5/3 = 1 2/3 = 1.6666
M4 and m2 are equivalent
M2 and m3 are supplementary angles which mean they add up to 180°
M2+m3=180
Plug in the equation
3x+74+2x+11=180
Add up the x’s 3x+2x=5x
Add the constants on the left side
74+11=85
You get 5x+85=180
Subtract 85 from both sides
5x=95
Divide by 5
X=19
Now plug x into the m3 equation and get
2*19+11=49°
Because m4=m3, m4=49°
M3 and m1 are equivalent so set both equations equal to each other and solve bringing the same variables on each side
11x-9=7x+23
11x-7x=23+9
4x=32
X=8
Now plug x into either equation and you get
M3=79°
