Answer:
Step-by-step explanation:
we know that
The perimeter of quadrilateral PQRS is equal to the sum of its four length sides
the formula to calculate the distance between two points is equal to
we have
the vertices P(2,4), Q(2,3), R(-2,-2), and S(-2,3)
step 1
Find the distance PQ
P(2,4), Q(2,3)
substitute in the formula
step 2
Find the distance QR
Q(2,3), R(-2,-2)
substitute in the formula
step 3
Find the distance RS
R(-2,-2), and S(-2,3)
substitute in the formula
step 4
Find the distance PS
P(2,4), S(-2,3)
substitute in the formula
step 5
Find the perimeter
substitute the values
The first thing he has to do is take that "minus" sign through the parentheses containing the second polynomial. Some students find it helpful to put a " 1 " in front of the parentheses, to help them keep track of the minus sign. Here's what the subtraction looks like, when working horizontally.
Answer:
F=2
Step-by-step explanation:
1.25f+2.75f=10-2
calculate like terms
4f=8
divide
F=2
It is 8 sq in his because if u use the formula bh1/2 u get 4 x 4 x 1/2 which is equal to 8
Answer:
C. 3
Step-by-step explanation:
To find slope you take one (y) and subtract another (y) then divide that by an (x) minus the other (x) so
8-5/2-1
3/1.
The slope is 3
