Answer:
The value of given expression for x = - 10 is - 81
Step-by-step explanation:
Given expression as :
3 
x - 2 
Or, 3 + x - 2 -
Or, 
x - 
or, 
Now for x = - 10
Or, 
∴ - 76 - 5
Or, - 81
Hence The value of given expression for x = - 10 is - 81 Answer
Easy peasy
400lb convert to oz
400 times 16=6400oz
6400/10=640
answer is 640 oz
C is answer
Answer:
5x-8y
Step-by-step explanation:
4x-9y+x+y
=4x+-9y+x+y
=4x+-9y+x+y
=(4x+x)+(-9y+y)
=5x+-8y
=5x-8y
Answer:
Radius = 7
Step-by-step explanation:
Since BA is tangent to circle O, it creates a 90° angle with the radius
Therefore, you can use Pythagorean theorem to solve this problem
a² + b² = c²
Let's say a is the radius
b is 5
c is 8.6
a² + 5² = 8.6²
a² + 25 = 73.96
Subtract 25 from both sides
a² = 48.96
Root both sides
a ≈ 6.997142274
The formula given to us relates circumference with radius but we are given diameter instead. good thing we know that diameter is twice the length of radius so if diameter=28, the radius=14. therefore, using our formula, we can find the circumference:
C = 2(pi)(14)
C = 87.96
and this answer is close to 88 so the answer is A
