(f+g)x = f(x)+g(x)

Therefore,

\frac{x}{4}  - 3 +  {4x}^{2}  + 2x - 4 \\ 4 {x}^{2}  + ( \frac{x}{4}  +  \frac{8x}{4} ) - 7 \\ 4 {x}^{2}  +  \frac{9x}{4}  - 7

Therefore, the answer is B.

masya89 [10]

Answer:

D. <b ≅ <g

Step-by-step explanation:

Given that lines p and q are parallel to each other, therefore the following can be concluded:

✔️<f ≅ <h, this is because they are both Vertical angles.

✔️<d and <h are supplematry, this is because they are same side consecutive interior angles. Consecutive angles are supplematry.

✔️<a and <b are supplematry, this is because they are linear pair angles.

✔️<b cannot be congruent to <g. They are not corresponding angles, nor are they alternate interior angles.

What is the length of the missing base of the trapezoid?
Eddi Din [679]

Answer:

6 inches

Step-by-step explanation:

Area = (base1 + base2)/2 · height

base1 = b

base2= 8

height = 3

Area = 21

21 = (b+8)/2 ·3

21 = 3(b+8)/2

multiply both sides by 2

42 = 3(b+8)

divide both sides by 3

14 = b+8

subtract 8 from both sides

b = 6 in
