Answer:

x and x+4

Step-by-step explanation:

since area is product of length and breadth for a rectangle . if we factorise the area given , take x as common the other expression comes out to be x+4 . hence dimensions are x and x+4

A parallelogram has sides of length 7.7 millimeters and 17.2 millimeters. What is the perimeter?

Answers

Solutions

We know that a rectangle has four sides and the perimeter of a rectangle is the distance around the outside of the rectangle.The opposite sides of a rectangle are congruent To find the perimeter you have to use the formula 2 × (Side A + Side B).

We have the side lengths 7.7 mm and 17.2 mm.

Solve

2 × (Side A + Side B)
2 × ( Side A (7.7) + Side B (17.2) )
= (7.7 x 2) + (17.2 x 2)
= 49.6

The perimeter is 49.6 mm².

P=2b+2c
P=2(7.7)+2(17.2)
P=15.2+34.4
P=49.6 millimeters

Mother is making two gallons of fruit punch how many pints o

f a punch he making?

Answers

Well let's turn this into an equation:

2g = p and g = 8 (because there are 8 pints per gallon)

2(8) = p

16 = p

Mother is making 16 pints of fruit punch.

For each gallon of fruit punch, there's 4 quart (1 gallon=4 quart) which is also 8 pints (1 quart=2 pints) so you multiply 8 pints by 2 which makes 16 pints
Remember this, 1 gallon is 8 pints

Which equation is identity? A.) 11-(2v+3)=-2v-8
B.) 5w+8-=6w-2 (w-4)
C.) 7m-2=8m+4-m
D.) 8y+9=8y-3

Ms smith has 28 sixth graders and 35 seventh graders for math. If she wants to break the two grades into identical groups without any students left over how many students will be I each group?

Answers

Ms Smith has 28 sixth graders and 35 seventh graders

she wants to break them down into groups with each group having the same number of students from each grade

for this we have to find the highest common factor of 28 and 35 to see by which both 28 and 35 are divisible by

factors of 28 and 35 are as follows

28 - 1,2,4,7,14,28

35 - 1,5,7,35

the highest common factor both numbers is 7

therefore Ms Smith can break them down into 7 groups

each group will have

28 / 7 = 4 sixth graders

35 / 7 = 5 seventh graders

so each group will have 4 sixth graders and 5 seventh graders

so in each group there will be 4 + 5 = 9 students

she will break them down into 7 groups

each group has 9 students

In this question, there is two class with a different number of students that need to be divided equally. Then you need to determine the number of greatest common factor (GCF) for both numbers. The number factor would be:
28= 7 x 2 x 2
35= 7 x 5

The only common factor in both numbers is 7, so making 7 groups will be the answer.
