2x^2-15=x
2x^2-x-15=0
(X-3)(2x-5)=0
x-3=0 or 2x-5=0
X=3 2x=5
x=5/2=2.5
Answer:
- R ⇔ T
- S ⇔ X
- T ⇔ Y
- RS ⇔ TX
- RT ⇔ TY
- ST ⇔ XY
Step-by-step explanation:
Corresponding parts are listed in the same order in the congruence statement:
RST ≅ TXY
R ⇔ T
S ⇔ X
T ⇔ Y
RS ⇔ TX
RT ⇔ TY
ST ⇔ XY
_____
Above, we have used ⇔ to mean "corresponds to."
Answer:
The answer to your question is 780 ft²
Step-by-step explanation:
- Divide the figure into two sections an upper part and a lower part.
- Area of the upper part = base x height
= 40' x 18'
= 720
-Area of the lower part
base = 40' - 30' = 10'
height = 24' - 18' = 6'
Area = 10 x 6 = 60
- Total area = Area Upper part + Area lower part
= 720 + 60
= 780 ft²
Answer:
See below.
Step-by-step explanation:
2(x-2) = 3x+3(2x+1)
2x - 4 = 3x + 6x + 3
2x - 3x - 6x = 3 + 4
-7x = 7
x = -1
