Answer:
Step-by-step explanation:
It is 40
Answer:
Width = 14m
Step-by-step explanation:
width = w
length = w - 6
area: w(w-6) = 112
w^2 - 6w = 112
14 x 14 = 196
6 x 14 = 84
196 - 84 = 112
6/7 because 48 divided by 8 is 6 and 56 divided by 8 is 7
Answer:
14 and 16.
Step-by-step explanation:
We know that two consecutive even numbers is 30.
Let's let n be <em>any number</em>.
Then the first <em>even</em> number must be 2n.
This is because n can be any number, either even or odd. However, if we multiply it by 2, this <em>ensures</em> that 2n is even. Remember that any number multiplied by 2 yields an even number.
Therefore, the consecutive even number will be (2n+2). Not (2n+1), because that gives an odd number.
We know that they sum to 30. So, we can write the following equation.
![(2n)+(2n+2)=30](https://tex.z-dn.net/?f=%282n%29%2B%282n%2B2%29%3D30)
And we solve from there:
![4n+2=30\\\Rightarrow4n=28\\\Rightarrow n=7](https://tex.z-dn.net/?f=4n%2B2%3D30%5C%5C%5CRightarrow4n%3D28%5C%5C%5CRightarrow%20n%3D7)
So, the value of n is 7.
Therefore, the first even number is 7(2)=14.
And the consecutive even number is 16.
