The perimeter is adding up all sides of a shape. Here we are told that the perimeter of the triangle is 41 inches. So we can make the equation:
Combine like terms(x + 3x = 4x):
We are also told that the perimeter of the rectangle is 66 inches. The formula for the perimeter of a rectangle is:
Plug in what we know:
Distribute 2 into the parenthesis:
So our system of equations is:
Let's use the substitution method to solve this system. Let's solve for 'x' in the second equation:
Subtract 14y to both sides:
Divide 6 to both sides:
Now let's plug this in for 'x' in the first equation:
Distribute:
Combine like terms:
Subtract 44 to both sides:
Divide -7/3 to both sides or multiply by its reciprocal -3/7:
So the solution to the system of equations is:
Plug these values in to find the length and width of the rectangle.
Length:
Width:
Answer:
3
Step-by-step explanation:
Determine the coefficient of y+ 6 - 3 in the binomial expansion y+ 3(2-1)
3(2+-1) + y = + 3(2) - (3)^-1 = 3
= y + 6 - 3 = y+3
remember to add a minus sign before every second term then a plus.
Now we see that in the term where y is in factor 3 as asked in the question (this is the term 2(3), the coefficient is therefore 3.
Step-by-step explanation:
Any number that can be divided by 2 without having remainder is considered an even number.
