Answer:

4x + 2

Step-by-step explanation:

x - 1 is adding an x and subtracting a 1 ,so

x + x + x + (x - 1) + 1 + 1 + 1

= x + x + x + x - 1 + 1 + 1 + 1 ← collect like terms

= 4x + 2

Given: line a is parallel to line b. Identify a pair of congruent corresponding angles.
UNO [17]

Answer:

Option

D . 4 & 8

Step-by-step explanation:

we know that

When two lines are crossed by another line (which is called the transversal), the angles in matching corners are called <u><em>corresponding angles</em></u>. If the two lines are parallel, the corresponding angles are congruent.

In this problem, the two lines are parallel

therefore

m\angle 1=m\angle 5 ----> by corresponding angles

m\angle 3=m\angle 7 ----> by corresponding angles

m\angle 2=m\angle 6 ----> by corresponding angles

m\angle 4=m\angle 8 ----> by corresponding angles

Can somebody help me <br> -2(x+5)
Anika [276]

Answer: -2x - 10

Steps: -2(x+5)

Apply the distributive law [ a(b + c) = ab + ac ]:

a = -2,  b = x,  c = 5

-2x + (-2) × 5

Apply minus/plus rules: -2x - 2 × 5

Multiply the numbers: 2 × 5 = 10

-2x - 10
