Answer:
[-9,3]
Step-by-step explanation:
The domain is all x-values or inputs of a function from left to right is -9 to + 3
Let me set an example to help solve this, say the poster is 100 inches by 90 inches. the length of the poster is reduced by 12% so subtract 12 from 100 to get you new length of 78 inches. the width is increased by 15% so multiply 90 by 15% to get 13.5 inches and add the to the 90 inches you have to get your new width of 103.5 inches. multiply them together to get your new area then divide the new area by the old area, subtract that number by 1 and multiply it by -1.
Answer : The length of an edge of cube is, 10 inches.
Step-by-step explanation :
The formula used for area of cube is:
Area of cube = 
where,
a = edge
We are given that:
Area of cube = ![600in^2[tex]Now put all the given values in the above formula, we get:Area of cube = [tex]6a^2](https://tex.z-dn.net/?f=600in%5E2%5Btex%5D%3C%2Fp%3E%3Cp%3ENow%20put%20all%20the%20given%20values%20in%20the%20above%20formula%2C%20we%20get%3A%3C%2Fp%3E%3Cp%3EArea%20of%20cube%20%3D%20%5Btex%5D6a%5E2)
Therefore, the length of an edge of cube is, 10 inches.
Answer:
x = -2 or x = -1/2
Step-by-step explanation:
We can just set up an equation where the quadratic is equal to -10, and then solve the equation:
Now, factor:
