F=1
Add 22 to both sides, then divide both sides by 3
Answer:
The answer to your question is: n = 95°
Step-by-step explanation:
The sum of the suplementary angles equals 180°
Then
121 + x = 180
x = 180 - 121
x = 59°
144 + y = 180
y = 180 - 144
y = 36°
The sum of the internal angles in a triangle equals 180°
x + y + z = 180
59 + 36 + z = 180
z = 180 - 59 - 36
z = 85
Finally
n + 85 = 180
n = 180 - 85
n = 95°

Answer: C. x+9</h3>
===============================================
Explanation:
Think of two numbers that multiply to -36 and also add to 5. Put another way: think of two factors of -36 that add to 5.
Those two numbers are 9 and -4 since
9 times -4 = -36
9 plus -4 = 5
So we have x^2 + 5x - 36 factor into (x+9)(x-4)
x+9 is one factor
x-4 is the other factor

Alternatively, you can use a graphing tool to locate the x intercepts, and that will in turn lead to the factorization. Or you could use the quadratic formula to get the job done. Completing the square is yet another tool to use. So there are multiple approaches.
Answer:
22.5
Step-by-step explanation:
Given:
The shape is a circle
Radius = 14 cm
To find:
The area and perimeter of the circle
Solution:
The value of π = 3.14
Area of the circle = πr²
= 3.14 × 14²
= 615.44 cm²
The area of the circle is 615.44 cm².
Perimeter of the circle = 2πr
= 2 × 3.14 × 14
= 87.92 cm
The perimeter of the circle is 87.92 cm.
