Answer:
38
Step-by-step explanation:
k= - 19 / - 0.5= -19*-2=38
Answer:
x = 3
Step-by-step explanation:
Let the altitude from B to AC intersect at point D. Then BD is a height of the triangle with base AC
ΔABD is a 30-60-90 triangle since m∠A = 30
Therefore, AB = 2(BD) or BD = AB/2 = (x+3)/2
Area of the triangle = bh/2 = AC(BD)/2 = 4x(x + 3)/(2)(2)
= x(x + 3) = 18
(x + 6)(x - 3) = 0
x = -6 or x = 3
x cannot equal -6, so x = 3
Y = 10
-4 * 10 = 40

Absolute value tells how many spaces the number is from 0. And opposite numbers are negative numbers on the left side of 0.
That's a trick question really because it depends on how you look at it on the conditions like chemistry, engineering and the value of any technical field. So if you have an option of saying both a and b are correct
