a rectangle has an area of 42 square inches which has a greater perimeter the rectangle with the dimensions 21 times 2 or the dimensions 6 times 7

Answers

Answer 1

Answer: A= 42in²
P = 2l + 2w so
(21 x 2) + (2 x 2)
42 + 4 = 46
46 = 21 by 2

Now let's do 6 and 7
(6 x 2) + (7 x 2)
12 + 14 = 26

46 > 26
so 21 by 2 has greater P (perimeter)

Answer 2

Answer: 21times 2 because it takes more work

B:five units to the right of 11
C:11 units to the left of zero
D:11 units to the right of zero

Answers

A is the answer. 5 units to the LEFT of 11. This is because even though the addition sign tells us to go the right side of the number line, the parenthesis number has a negative sign. Multiplying the signs will give 11-5 which will ask us to got LEFT of the number 11 on a number line.

Answer:

5 units in the negative direction.

First of all, don't cry. Second of all, try to post a clearer picture because it was a bit tough to see. Third of all, here are the answers:

In row 9, S is wrong because it is 27x+24y, it should be 36x+24y
In row 10, A is wrong because it is 4+20x, it should be 20x
In row 11, G is wrong because it is 15ab, it should be 10a+5b
In row 12, I is wrong because it is 15x+6y, it should be 15x+10y
In row 13, O is wrong because it is 22a+6, it should be 28a
In row 14, T is wrong because it is 14x, it should be 22x
In row 15, K is wrong because it is 15x+y, it should be 15x+3y
In row 16, T is wrong because it is 14n+84m, it should be 12m+14n

Also on another note, this might be intimidating but it is mostly adding/multiplication of variables. So if you don't know them, you might want to double check that you know how to handle variables in the future;)

The surface area of a square pyramid is 136 square inches. The base length is 4 inches. What is the slant height? please help!

Answers

the surface area is 136

you need to subtract the surface area of the base. It is a square pyramid, so both the sides are 4 inches, meaning you need to multiply 4x4 which is 16 and subtract it from the rest of the area. 136-16=120

There are four identical triangles that have identical surface area because it is a square triangle. So you can divide 120 by four to get the area of one of the triangles. 120/4=30

the formula for the area of a triangle is 1/2 base x height. We know that the base is 4 because that is the length that was given to us. so we can plug in our numbers into the formula

30=1/2(4)(height)

30=2(height)

and from there we can solve. 30/2=15

the height of the triangle is 15, which is also the slant height

to check our work, 1/2(4)(15)=30

4x15=60

1/2x60=30
