QUESTION POSTED AT 18/01/2020 - 07:41 AM

For this question the answer is 2.5m (B)

You find this by: L=0.85m

W=0.4m

A rectangle had 4 sides (2 lengths and 2 widths)

So...

To find 1 length and 1 Width you do 0.85+0.4=1.25m

Now you want to find the other 2 sides (L and W)

You can do: the same method and add it to 1.25m OR...

You can do (I prefer this one): (0.85+0.4)x2=?

This is the same as 0.85+0.4=1.25

1.25x2=2.5m

You find this by: L=0.85m

W=0.4m

A rectangle had 4 sides (2 lengths and 2 widths)

So...

To find 1 length and 1 Width you do 0.85+0.4=1.25m

Now you want to find the other 2 sides (L and W)

You can do: the same method and add it to 1.25m OR...

You can do (I prefer this one): (0.85+0.4)x2=?

This is the same as 0.85+0.4=1.25

1.25x2=2.5m

The answer to this question would be:

Jim =6 years

Harry =2 years

To answer this question, you need to translate the description into a mathematical equation. If H= Harry's ages and J= Jim's ages, then the equation should be look like this:

1. H+4= J

2. (J+2)= 2(H+2)

J+2= 2H+4

J= 2H +2

If you put the 1st and 2nd equation together, the result would be:

H+4= J

H+4= (2H +2)

H-2H= 2-4

-H= -2

H=2

After that insert the H value to either 1st or 2nd equation.

H+4= J

2+4=J

J= 6

Jim =6 years

Harry =2 years

By the given scenario above, we can formulate two inequalities that best represent the scenario. We let x and y be the number of tables and chairs, respectively such that,

25x + 15y ≤ 285

x + y ≥ 16

The values of x and y if we temporarily change all the inequality signs to equal signs are 4.5 and 11.5, respectively. Since, it is not allowed for a number of item to be in negative, we can then say that the number of tables should be 4 and that of chair is 12.

Range is how far up or down the garph can go

basically the limits of y

find min and max of y

basically find the biggestor smallest the x can get to influence y

confusing sorry

when x is an even number, that number is still negative

so make that number as small as possible

if x=(big number that is negative)

we get -1/(5^(big number)) which basically makes it nigligible or almost 0

y=-7 is max

when x=big number (positive) we get very negative number

so range is from negative infinity to -7

basically y<-7

we choose < and not ≤ because the -5ˣ will never dissapear, it will just be very, very small

y<-7 is answer

**Answer:**

**Area of square is 25 inches² **

**Step-by-step explanation:**

Given : A square photograph has a perimeter of 20 inches.

We have to find the area of the photograph.

**We know perimeter of square is 4a , where a is side of square**

Given : perimeter of square = 20 inches

4a = 20

Divide both side by 4, we get,

**a = 5 inches**

**Also, Area of square = side × side **

Area of square = 5 × 5

Area of square = 25 inches²

**Thus, area of square is 25 inches² **
