Answer:
6 square inches
Step-by-step explanation:
The area of the triangle is
A = 1/2 bh where b is the base and h is the height
b= 4 inches and h = 3 inches
A = 1/2 * 4* 3
A = 1/2 * 12
A = 6 inches ^2
Answer:
15°
Step-by-step explanation:
AB is parallel to DC and AD is parallel to BC
Therefore, if you put Angle D and Angle C together it must form 180°
If Angle C = 120°, that means Angle D = 60°
Now you subtract 45 from 60 and that gives you 15.
Answer:
The function
f(x) = x3 + 2x2 − x − 2
is a trinomial and it is expected that it has three factors corresponding to the three roots. The possible roots could 1, -1, 2, or -2. Trying out 1
f(1) = 1 + 2 - 1 - 2 = 0
According to the remainder theorem (x - 1) is a factor. By doing synthetic division
1 | 1 2 -1 -2
1 3 2
1 3 2 0
f(x) = (x - 1)(x2 + 3x + 2)
which can further be factored into
f(x) = (x -1)(x +1)(x + 2)
The three factors are
x-1
x+1
x+2
which are all linear expressions
