For question 9 - It is stating that AE is equal to 38. So the length of the entire line is 38. We then need to look at which figures are actually useful to us, which in this case is AC which is 10. Therefore the answer is as simple as 38-10, which gives us an answer of 28 for the other half of the line, notated as CE.

Area of regular polygons
Finger [1]
Hello!

To find the area of a hexagon you do 3\frac{3 \sqrt{3} }{2} } a^{2} where a is one of the sides

Since the perimeter is 60 we can do 60/ the sides of the shape

60/6 = 10

So one side is equal to 10

you put that into the formula to get the area of a hexagon and you get 259.81

Hope this helps!

Angelina wants to buy the same number of pens and pencils. Pens come in 8 packs and pencils come in packs of 9. What is the leas
andrew11 [14]

Answer:

Angelina should buy 9 packs of pens and 8 packs of pencils.

Step-by-step explanation:

Each pack of pens = 8 pens

Each pack of pencils = 9 pencils.

Also we know that, Commutative Property of Multiplication states that

a x b = b x a for any two numbers a and b.

So, 8 x 9 = 72 = 9 x 8

Hence, she should buy 9 packs of pens, so she will have 9 x 8 = 72 pens.

And she should buy 8 packs of pencils, she will have 8 x 9 = 72 pencils.

How many solutions can be found for the linear equation? 4(x + 5) - 5 = 8x + 18/ 2
mylen [45]

Answer: The correct option is A.

Explanation:

The given equation is,

4(x+5)-5=\frac{8x+18}{2}

Multiply both sides by 2.

2[4(x+5)-5]=\frac{8x+18}{2}

8(x+5)+2(-5)=8x+18

8x+40-10=8x+18

8x+30=8x+18

Subtract both sides by 8x.

30=18

This statement is false for any value of x, therefore the system of equation have no solution and option A is correct.
