Answer:
117
Step-by-step explanation:
Distribution means that we multiply the 9 to both numbers within the parentheses.
So, first, we can multiply and we get 36. Then we multiply to get 81. Distributing gets rid of the number on the outside of the parentheses, in this case, 9. So now we just have the numbers within the parentheses: . Simplify from there and you get 117.
I hope this helps!
It should be understood that intersecting lines do not necessarily are perpendicular, these are called skew lines. Perpendicular lines are lines that form right angles or 90 degrees when they intersect at a point. In this case, the answer to this problem is C.
Answer:
x = 80° , y = 50° , a = 60° , p = 60°
Step-by-step explanation:
(a)
a linear pair of angles sum to 180° , then
x + 100° = 180° ( subtract 100° from both sides )
x = 80°
(b)
vertically opposite angles are congruent , then
y = 50°
(c)
complementary angles sum to 90° , then
a + 30° = 90° ( subtract 30° from both sides )
a = 60°
(d)
supplementary angles sum to 180° , then
p + 120° = 180° ( subtract 120° from both sides )
p = 60°

Would be: 76 - (13 + 2*7)
76- (13+14)
76-27=49
