Answer:
112
Step-by-step explanation:
So, we know that a triangle's sides must add up to have a sum of 180. If you add up your given lengths and you should get 47, not including x. Then if you look at the left side/the one without a given length and it should be identical to the 21, so you know that side is 21. So now add 21 to 47, you should get 68. Finally, you subtract 68 from 180 like this: 180-68, and it should equal 112. So you're answer is 112.
Answer:
y = 45/m^2 − 49/4
Isolate the variable by dividing each side by factors that don't contain the variable
Answer:
There are 59.66 inches in the circumference of the large pizza.
Step-by-step explanation:
It is given that:
Diameter of Joe's large pizza = 19 inches
Diameter = 2r
2r = 19
Circumference of large pizza = 2πr = 2r * π
Circumference of large pizza = 19*3.14
Circumference = 59.66 inches
Therefore,
There are 59.66 inches in the circumference of the large pizza.

Answer:
Option D. is correct.
Step-by-step explanation:
Let us assume that x = seven square root three plus two square root nine
i.e. x = 7√3 + 2√9
⇒ x = 7√3 + 2 × 3 {Since 9 = 3²}
⇒ x = 7√3 + 6
Here, 7√3 is an irrational number and 6 is a rational number.
The answer is seven square root of three plus six is irrational because the sum of a rational number and an irrational number is an irrational number.
Therefore, option D. is correct.
