Answer: 3n-6
Step-by-step explanation: You have to use the distributive property. 3 times n is 3n and 3 times -2 is -6.
Answer:
66 square inches
Step-by-step explanation:
The area of the figure can be found by adding the area of the rectangle and the triangle together.
The area of a rectangle is found A = l*w. Here l = 10 and w = 6. So the area of the rectangle is 10*6 = 60.
The area of a triangle is found A = 1/2 b*h. Here b = 2 from 12-10 = 2 and h = 6. So the area of the triangle is 1/2 * 2* 6 = 6.
The area together is 60 + 6 = 66 square inches.
The answer would be if you were solving for y. Y= 1/2x+3/8
Answer:

Step-by-step explanation:

Answer:
Question #1
m∠4 + m∠7 = 180° - Given.
∠4 and ∠7 are supplementary angles - Definition of supplementary angles.
∠7 and ∠2 form a linear pair - Definition of linear pair.
∠7 and ∠2 are supplementary angles - Definition of linear pair.
m∠7 + m∠2 = 180° - Definition of supplementary angles.
m∠2 = m∠4 - Substitution property.
c ║ d - Converse of corresponding angles postulate.
Question #2
m∠3 = m∠8 - Given.
∠8 and ∠6 form a linear pair - Definition of linear pair.
∠8 and ∠6 are supplementary angles - Definition of linear pair.
m∠8 + m∠6 = 180° - Definition of supplementary angles.
∠3 and ∠6 are supplementary angles - Substitution property.
m∠3 + m∠6 = 180° - Definition of supplementary angles.
Question #3
p ║ q - Given.
∠1 ≅ ∠5 - Given.
∠1 ≅ ∠2 - Alternate interior angle theorem.
∠2 ≅ ∠5 - Substitution property.
