ax²+bx+c=0
4a²x²+4abx+4ac=0
4a²x²+4abx=-4ac
4a²x²+4abx+b²=b²-4ac
(2ax+b)²=b²-4ac
Answer:
t=10.9
Step-by-step explanation:
8t-13t+10(t-2)=34
8t-13t+10t-20=34
5t-20=34
5t=54
t=10.9
Answer:
A.T.Q
first we need to open the bracket
,when we open breaket the sign in the bracket will change
so the question is
- g - 4 + 2g + 6
now, we take like terms together
- g + 2g - 4 + 6
g + 2 is the answer by solving
Each angle is 90 degrees because 90 times 3 is 270.
Side 1 = short side = 2x-3
side 2 = longer side = (short side) + 6 = (2x-3)+6 = 2x+3
side 3 = side 2 = 2x+3
Side 2 and side 3 are the longer two congruent sides
Add up the three sides and set them equal to the given perimeter of 33. Solve for x
(side1)+(side2)+(side3) = perimeter
(2x-3)+(2x+3)+(2x+3) = 33
(2x+2x+2x) + (-3+3+3) = 33
6x+3 = 33
6x+3-3 = 33-3
6x = 30
6x/6 = 30/6
x = 5
If x = 5, then the longer sides are 2*x+3 = 2*5+3 = 10+3 = 13 inches each
(note: the short side is 2*x-3=2*5-3=10-3 = 7 inches)
Answer: 13 inches
