Step-by-step explanation:
Answer:
23
Step-by-step explanation:
the angles are equal to each other so we use the equation
6x-7=9x-22 and solve for x
step 1 subtract 6 from each side
-7=3x-22
step 2 add 22 to each side
3x=15
step 3 divide each side by 3
x=5
then to find the angle abd we plug in 5 to 9x-22
9x5=45
45-22=23 so angle abd=23
hope this helps (:

If you pour out 1/4 of the water and it’s 7 gallons, then 7 x 4 ( or 7/.25) = 28 gallons.
Answer:
11.19ft * 15.19ft
Step-by-step explanation:
Width = x
Length = x-4
Area = 170ft2
Area of a rectangle = Length * Width
170ft^2 = (x-4) * x
x(x-4) = 170...........equation(1)
x^2-4x-170 = 0......equation(2)
Using the quadratic equation(for equation 2),
-b+-sqrtb^2-4ac/2a
from equation(2): a=1x=1
b= -4
c= -170
thus, x= 4 + sq.rt696/2 = 4 +26.38 =30.38/2=15.19
