Answer:
4th option OR last option
Step-by-step explanation:
Ok so I think it means hexagon not heptagon since I have never heard of heptagon. Just confirm that with your teacher if it is hexagon or heptagon.
Hexagon = 6 sides
This means that it is not second option. Nor it is the third option since it said that it should be more than 6 sides. Now we are left with 1st and 4th option. It also mentioned that all opposite sides should be parallel. Looking at the first option, not all sides are parallel. Some are big and some are small. This remains with the last option which is the 4th option.
Hope this helps, thank you !!

y=-4x-9 y=3x+19
Answers
Answer:
x=-4, y=7
Step-by-step explanation:
According to the first equation, y = -4x - 9, so we can substitute y in the second equation for -4x - 9.
y = 3x + 19
-4x - 9 = 3x + 19
Add 9 to both sides
-4x = 3x + 28
Subtract 3x
-7x = 28
Divide by -7
x = -4
Plugging this into the equation, we have:
y = -4x - 9
y = -4(-4) - 9
y = 16 - 9
y = 7

seeta devi has rs 9 in fifty-paiseand twenty fiv-paise coins. She has twice as many twenty-five paise coins as fifty-paise coins.How many coins of each kind does she have?
Answers
Answer:
50 paise coin = 9
25 paise coin = 18
Step-by-step explanation:
Let :
Number of fifty paise = x
Number of 25 paise = y
50x + 25y = 900 - - - (1)
y = 2x - - - (2)
50x + 25(2x) = 900
50x + 50x = 900
100x = 900
x = 900/100
x = 9
y = 2x
y = 2(9)
y = 18

Which expressions are equivalent to Negative 9 (two-thirds x + 1)?
Check all that apply.
Negative 9 (two-thirds x + 1) can be expressed as:
-9(2/3x + 1)
Expanding the brackets
(-9 × 2x/3 + 1 × -9)
-6x - 9
Therefore, the expressions that are equivalent to Negative 9 (two-thirds x + 1) is:

Mr. Strand mowed 2/5 of his lawn. His son mowed 1/4 of it. Who mowed most of the lawn? How much of the lawn still needs to be mowed?
Answers
Answer: Mr. Strand mowed most of the lawn, and 7/20 of the lawn still needs to be mowed.
Step-by-step explanation:
Part 1:
We can use change the fractions so that they have equivalent denominators. The Least Common Denominator that the two fractions have is 20.
2/5 = 8/20.
1/4 = 5/20.
Because of this, Mr. Strand, who mowed 2/5 of the lawn, mowed most of the lawn.
Part 2:
8/20 + 5/20 = 13/20. Therefore, 7/20 of the lawn still needs to be mowed.
In conclusion, Mr. Strand, who mowed 2/5 of the lawn, mowed most of the lawn. 7/20 of the lawn still needs to be mowed.
Answer:
Step-by-step explanation:
0.65 of the lawn was mowed
Factor out the greatest common factor of Given the expression: 4x^10 − 64x^2
Answers
Part A
4x10 – 64x2
= 4x2 * x8 – 4x2 * 16
= 4x2 * (x8 – 16) by distributive property
Part B
x8 is (x4)2 and 16 = 42 so a difference of squares is seen in the parentheses. The pattern a2 – b2 = (a + b)(a – b) can be used.
4x2 * (x8 – 16)
= 4x2 * (x4 + 4) * (x4 – 4)
x4 = (x2)2 and 4 = 22 so there is another difference of squares in the last factor. Use the pattern again.
= 4x2 * (x4 + 4) * (x2 + 2) * (x2 – 2)
Answer:
Below.
Step-by-step explanation:
The GCF = 4x^2
So its 4x^2(x^8 - 16)
This can be further factored
= 4x^2(x^4 - 4)(x^4 + 4)
= 4x^2(x^2 - 2)(x^2 + 2)(x^4 + 4)

luca sells muffins and juice boxes. muffins are $1.50 each and jucie boxes are $1.25 each. write an algebraic expression for the total income luca received from the sale of muffins and juice boxes
Answers
Answer:
1.5m+1.25j
Step-by-step explanation:
m equals the number of muffins sold, and because each muffin sells for $1.50, 1.5m represents the income made from the muffins.
Same thing with the juice boxes, j equals the number of juice boxes sold, and because each juice box sells for $1.25, 1.25j represents the income made from the juice boxes.
Add the income from both of them to get the total income, and you get 1.5m+1.25j.

the hypotenuse of a triangle is 5in and leg one is 4in how long is leg two
Answers
a^2+16=25
I squared the numbers 4times4=16 and 5times5=25
Now you minus 16 because we are trying to figure out what “a” is or other words leg two
So 25-16=9
Now a is still square so be got to take the square 2 away and square 2 is also know as square root so a= 3 the other leg is 3
Check
3^2+4^2=5^2
9+16=25
25=25
