Given:
Area of rectangle = 
Width of the rectangle is equal to the greatest common monomial factor of 
.
To find:
Length and width of the rectangle.
Solution:
Width of the rectangle is equal to the greatest common monomial factor of is
Now,
So, width of the rectangle is 
.
Area of rectangle is
Taking out GCF, we get
We know that, area of a rectangle is the product of its length and width.
Since, width of the rectangle is , therefore length of the rectangle is 
.
I simply divided by 100 and moved the decimal two places to the left.
There are 66 elephants in the safari.
Solution:
The number 88 refers to both elephants and giraffes that are in the safari. We know that the number of elephants is thrice the number of giraffes. So we can let x be the number of giraffes and 3x be the number of elephants.
We will then come up with the following equation:
3x + x = 88
Then, just add the two variables, and continue the operation.
4x = 88
x = 88/4
x = 22
Now we know that there are 22 giraffes in the safari. So 3x, or 3(22) = 66. There are 66 elephants in the safari.
F(x) = 1.8x - 10.....g(x) = -4
f(x) = g(x)
1.8x - 10 = -4
1.8x = -4 + 10
1.8x = 6
x = 6 / 1.8
x = 3.33 or 3 1/3
