Substitute in what you already know into the formula, since the formula is (a=bh) you already know what A is so now you have 50=bh, now the length is x+7 , length is basically height , so h in the formula , so now you get 50=b(x+7) , now you need b luckily you already have b, so plug in 50=(x+2)(x+7) , you can guess and check or you can solve for x by double distributing
(a+b)²=a²+2ab+b²
(x+6)²=x²+2× x × 6+6²=x²+12x+36
hope this helps :)
Answer:
108π yards
Step-by-step explanation:
So the volume of a cone is πr^2 * h / 3
r = 6 yards
h = 9 yards
36π * 3 = 108π yards
Hey there :)
To find the slope with <em>two points</em> we will need to use the equation
( 3 , -20 ) ( 5 , 8 )
Here is what the equation should look like when replaced with the numbers (<em>it will be a fraction</em>) :
We know that <em>two negatives</em> cancel out and make a positive, so the numerator would actually be 8 + 20.
Solve the fraction and we get
28 <em>divided</em> by 2 is 14. The slope is 14.
C; since this is a function of N you are replacing N for 10
