Add 1 to both sides:
In cases like this, we have to remember that a root is always positive, so we can square both sides only assuming that
Under this assumption, we square both sides and we have
The solutions to this equation are
But since we can only accept solutions greater than -1, we discard 
and accept 
.
In fact, we have
and
which is the only solution.
Answer:
this makes no sence you said 2x+3=-8 if x =-8 then the answer would be
2x-8+3=-8 ??? that is not correct
Step-by-step explanation:
Plug in x-values and see which one has an incorrect y value.
(x, y)
x=0; y=0+7=7; CORRECT
x=2; y=2+7=9; INCORRECT
x=9; y=9+7=16; CORRECT
x=12; y=12+7=19; CORRECT
The point that is not on the online is (9, 16).
Answer:
x² - 4x + 12
Step-by-step explanation:
x=2+2.82843i
x=2−2.82843i
Answer:
SA = 76 yd²
Step-by-step explanation:
Use the formula given:
- SA = 2(4)(2) + 2(4)(5) + 2(2)(5)
- SA = 16 + 40 + 20
- SA = 76
The units are yards²
SA = 76yd²
