Answer:
A: 12:18
Step-by-step explanation:
Answer:
x = 50°
y = 50°
z = 80°
Step-by-step explanation:
working out x:
angles on a straight line add up to 180°
x + 130° = 180°
subtract 130 on both sides
x = 180° - 130°
x = 50°
working out y:
two vertical lines means that both sides are equal, so both angles are also equal (it's an isosceles triangle). This means that y is the same angle as x = 50°
y = 50°
working out z:
the sum of a triangle add up to 180°
add up the angles of x and y and equate to 180°
50 + 50 + z = 180
100 + z = 180
subtract 100 on both sides
z = 180 - 100
z = 80°
Answer:
- 2(x - 6)(x - 4)
Step-by-step explanation:
Given
- 2x² + 20x - 48 ← factor out - 2 from each term
= - 2 (x² - 10x + 24) ← factor the quadratic
Consider the factors of the constant term (+ 24) which sum to give the coefficient of the x- term (- 10)
The factors are - 6 and - 4, since
- 6 × - 4 = + 24 and - 6 - 4 = - 10, thus
x² - 10x + 24 = (x - 6)x - 4) and
- 2x² + 20x - 48 = - 2 (x - 6)(x - 4) ← in factored form
