Answer: A) x + 4x = 35; 7 large stones and 28 small stones
======================================================
Explanation:
x = number of large stones
4x = number of small stones
x+4x = total number of stones = 35
x+4x = 35 is the equation to solve
-----------
Let's isolate x
x+4x = 35
5x = 35
x = 35/5
x = 7 large stones are needed
4x = 4*7 = 28 small stones are needed
(x+2)(x+1) = x^2 + x + 2x + 2
simplify it
x^2 + 3x + 2
First you need to put it into y=mx+b format and which is 1/2x + 2 =y. The y intercept should be b in the equation y=mx +b so y=2. The x-intercept should be when y=0 and x equals a number which is x=-4. X-intercept=-4 and y-intercept=2.
Answer:
15x is your answer. Hope this helps.
