Hey DatGamer13!
Question:
Solve for x
Solution:
Subtract 10 from both sides.
3x^2 + 13x − 10 = 10 − 10
3x^2 + 13x − 10 = 0
Factor left side of equation.
(3x − 2) (x + 5) = 0
Set factors equal to 0.
3x − 2 = 0 or x + 5 = 0
Answer:
x = 2/3 or x = −5
The answer would be 42 because its the same angle as the other one
I hope I helped! ♥
Answer:
x = 20°
y = 70°
Step-by-step explanation:
the angle adjacent to the 40° angle must be 140° because the two angles form a straight line (which contains 180°)
in the isosceles triangle with the 'x', that means the other two angles must be equal and are (180-140) ÷ 2, which equals 20°
to find 'y', consider the larger right triangle with angles of 90° and 20°; angle y must equal 180 - (90 + 20) = 70°
Answer: Option C
Step-by-step explanation:
Given the quadratic equation 
, substitute 
:
In this case, to find the solutions of the given quadratic equation, you must factor out the variable "x". Then:
Therefore, you get that the solutions of this equation are the following:
Then, the answer is:
This matches with the option C.
