Gg easy
remember
for
ax^2+bx+c=0
first
minus c from both sides
ax^2+bx=-c
divide both sides by a (disregard if a=1)
take 1/2 of b and square it and add that to both sides
factor perfect square
ok so
x^2-3x=-1
-3/2=-1.5
(-1.5)^2=2.25
add that to both sides
x^2-3x+2.25=2.25-1
factor
(x-1.5)^2=1.25
Y = 9
7y - 10y = -3y
bring down the 9 = -18 so
-3y + 9 = -18
9 - 9 = 0
- 18 - 9 = - 27
- 3y ÷ - 3 = y
- 27 ÷ -3 = 9
therefore y =9
Answer:
20 degrees.
Step-by-step explanation:
The interior angles of a triangle add up to 180 degrees. One of them, bottom right, is already shown as 70 degrees. You can find the bottom left angle by subtracting 110, the supplementary angle, from 180 (the number of degrees in a straight line). The top angle, 2x, is equal to 40 degrees. (180-70-70 = 40). 40/2 = x, so x = 20 degrees.
Answer:
432 feet squared
Step-by-step explanation:
area = L ( W)
area = 24(18)
area= 432 feet squared
The two numbers are -1 and -16.
-1+(-16)= -17
-1*(-16)= 16
Hope this helps~
