Answer:
42cm²
Step-by-step explanation:
because if the perimeter of the rectangle is 28 then the length is 5, 5 - 11 = 6, the formula for finding the trapezium is to add the 2 parallel sides, half them, then times them with the length so your sum will look like this, 5+9=14, (i knew the other side was 9 as the length of AB is the same as the length of FC, which is the one of the parallel sides of the trapezium) then we do 14÷2=7, finally we times 7 by 6 which is 42cm²
X=6 because 3X6=18 so x=6
The slope of the linear equation is 0.37, then the linear equation will be represented as y = 0.37x + 4.
<h3>What is the linear system?</h3>
A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.
If Sandra charges $4.00 for a cup of ice cream and $0.37 for each ice cream. Then the linear equation is given as
We have
m = $0.37
c = $4
Then the linear equation will be
y = 0.37x + 4
