Answer:
30 ft
Step-by-step explanation:
Multiply the scale factor by the wall given.
45 X 8 in = 360 in
Convert inches into feet. (12 inches = 1 foot)
360/12 = 30 feet
Answer:
90
Step-by-step explanation:
its half
Well you are given the roots.
if we have 3 it would.have to be x^3. So something like:
y = ax^3 + bx^2 + cx + d
this could.also be written:
y = (x + a) (x + b) (x + c)
when you are able to write it like this, we know that the opposite of a, b, and c are roots. this is because if we can make any of the insides of the 3 parenthesis equal 0 then y = 0 and that x.is a root. Well if we know the 3 roots that x will be then we just have to figure out the a, b, and c. So let's plug our roots in.
y = (-1 + a) (-5 + b) (-3 + c)
now we have to make each parenthesis equal 0 to find what a, b, and c should be. It is obvious a = 1 to make.that one zero and b = 5 and c = 3. So we know a, b, and c. now let's plug.those into our first equation.
y = (x + 1) (x + 5) (x + 3)
this is your equation. You can multiply out if necessary
Its letter b. it includes an investment opponent
It has given you that to earn $85 in one week. Kim could earn $8 per hour babysitting and $15 per hour for yard work with work time limited to 8 hours per week. Now we have to represent the variable X is the numbers of hours spent doing babysitting in the week. And Y represents the number of hours spent doing yard work in the week. The equation representing the condition on the total number of hours to be worked is: x+y= 8. The equation relating the number of hours working at each job toward the fund- raising goal is: 8x+ 15y= 85 and your final answer should be x= 5
