A triangle always adds up to 180 degrees:
Therefore, 48 + 6x + 9x-3 = 180
Solve for x:
180 - 45 = 15x
135 = 15x
x = 9 degrees
Answer:
dont know what the expressions are but imma just guess its doing scientific notation, 8.73 x 10^-11
Step-by-step explanation:
Answer:
(- 2, 0 ), (1, 0 )
Step-by-step explanation:
Given
y = 2x² + 2x - 4
To find the x- intercepts let y = 0, that is
2x² + 2x - 4 = 0 ← divide through by 2
x² + x - 2 = 0 ← in standard form
(x + 2)(x - 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 2 = 0 ⇒ x = - 2
x - 1 = 0 ⇒ x = 1
Thus x- intercepts are (- 2, 0) and (1, 0)
Answer:
True.
