Answer:
A= 4 , B= 3
Step-by-step explanation:
Simply put, use systems of equations to solve for A and B. First make y equal 4, and to make A equal to four, while being multiplied by 1 it has to be 4. Then solve backwards and now you know that A equals four, what multiplied by 4 is equal to 36, 9. What is the square root of 9? 3!
Answer:
34
Step-by-step explanation:
Substitute 8 where there is an x
f (8)= 4(8) +2
= 32 +2
=34
Answer:
the answer is the 2nd, 3rd, and 4th ones
Step-by-step explanation:
(35 + 47 + 42 + x) / 4 = 50
(124 + x) / 4 = 50....multiply both sides by 4, cancelling the 4 on the left side.
124 + x = 50 * 4
124 + x = 200
x = 200 - 124
x = 76 <===
Answer:
Triangle
Step-by-step explanation:
A triangle has three vertexes, and therefore three interior angles. Those angles also sum to 180 degrees because of the formula (n-2)*180, where n is the number of sides that a polygon has. Plugging in 3, you get 
, or just 180 degrees. Hope this helps!
