Answer:
x=70
y= 30
z= 10
Step-by-step explanation:
X + 110 = 180 since they form a straight line
Subtract 110 from each side
x+110 -100 = 180-110
x = 70
Y + 110 + 40 = 180 since the three angles of a triangle add to 180
y+150 = 180
Subtract 150 from each side
y+150-150 = 180-150
y = 30
A + B+ C = 180 since the three angles of a triangle add to 180
90 + y+z+ 40 =180
90 + 30+z + 40=180
Combine like terms
170 +z = 180
z = 180-170
z = 10
f(x) = x³ - 2x² - 24x
x³ - 2x² - 24x = 0
x(x² - 2x - 24) = 0
x = 0
x² - 2x - 24 = 0
a = 1, b = -2, c = -24
Delta = (-2)² - 4 * 1 * (-24) = 4 + 96 = 100
x = (-(-2) - 10)/(2 * 1) = -8/2 = -4
x = (-(-2) + 10)/(2 * 1) = 12/2 = 6
Answer: 2)
Answer:
3 miles = 5280 yds
5280 yds > 5,000 yds
in this case 3 miles is greater than 5,000 yards
The answer would be B. because the first part is half the cost of deandra's sofa is x divided by 2, and the second part is 30 dollars less which you subtract the first part minus the second part. x/2 - 30
Answer:
Let's cut the figure into:
Parallelogram, square, and rectangle.
Let's find the area of the parallelogram first:
10 x 3.5 = 35
Let's find the area of the square:
4 x 4 = 16
When given one length of a square you already know are sides and lengths are equal so therefore 1 given length of a square is all the lengths.
Let's find the area of a rectangle:
6 x 12.5 = 75
Now let's add all the areas up:
35 + 16 + 75 = 126 square inches is your answer.
