Answer:
1.
m<MNQ =m<P+m<Q exterior angle of a triangle is equal to the sum of two opposite interior angle
2;
132°=3x+54°
3:
132-54=3x
x=78/3
x=26°
4(x+8)-4=34-2x steps
4x + 32 - 4 = 34 - 2x
4x + 28 = 34 - 2x
4 x + 2 x = 34 - 28
6 x = 6
x = 6/6
x = 1
Step-by-step explanation:
Let n be the age of the youngest sister. Since the ages are consecutive odd integers, the next sister's age is n+2, and the oldest sister is n+4. the following equation represents the relationship between the girls' ages.
n + 3(n + 4) = 5(n + 2) - 5
n + 3n + 12 = 5n + 10 - 5
4n + 12 = 5n +5
-4n -5 -4n -5
7 = n
so the sisters are 7, 9, and 11

Step-by-step explanation:
to evaluate f(a) substitute x = a into f(x)
f(a) = 5a + 4
---------------------
2f(a) = 2(5a + 4) = 10a + 8
-----------------------
to evaluate f(2a) substitute x = 2a into f(x)
5(a + 2) + 4 = 5a + 10 + 4 = 5a + 14
--------------------------
f(a) + f(2) ← substitute x = 2 into f(x)
= 5a + 4 + 5(2) + 4 = 5a + 4 + 10 + 4 = 5a + 18
The answer is A
A Parallelogram is a shape with 4 sides that has two pairs of parallel sides. The opposite sides must have equal length. This is accurate for this shape.
A Rectangle is a shape with 4 sides that has four right angles. This is accurate for this shape.
A rhombus is a shape with 4 sides of equal length. This is not accurate for this shape.
A square is a shape with 4 sides of equal length and four right angles. This is not accurate for this shape.
