Answer:
x = - 3, x = - 2
Step-by-step explanation:
Given
x² + 5x + 6 = 0
Consider the factors of the constant term (+ 6) which sum to give the coefficient of the x- term (+ 5)
The factors are + 3 and + 2, since
3 × 2 = + 6 and 3 + 2 = + 5, thus
(x + 3)(x + 2) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 3 = 0 ⇒ x = - 3
x + 2 = 0 ⇒ x = - 2
Answer:
139
Step-by-step explanation:
first you need to find the x:
180= 8x + 51 + 6x - 25
180 - 51 +25 = 8x + 6x
154 = 14x
154/14 = x = 11
then you have to work out AOB:
8x +51
8(11) +51
88+51 = AOB = 139
to check your work, workout angle BOC and add both. angles together to check if you get 180:
BOC= 6x - 25
6(11) - 25
66 - 25 = 41
To check:
BOC + AOB = 180
41 +139 = 180
180 = 180
Hope this helps!

Answer:
The answer is D i guess . ( Not completely sure )
Answer:
first use the Pythagoras theorem to find for a,b and c
that is. c²= b²+a²
then when you find the answers find the area of A,B and C
that is <u>1</u>× base × height
