Which expression is equivalent to
(4x³ + 5x² + 2) + (3x² - 7x + 4)?
Answer:
4x³ + 8x² - 7x + 6
Step-by-step explanation:
remove the brackets by distributing the sign.
4x³ + 5x² + 2 + 3x² - 7x + 4
4x³ + 8x² - 7x + 6
Gather like terms.
If you want to factorise (optional)
4x³ + 8x² - 7x + 6 =
4x²(1 + 2x) - 6x + 3 + 3 - x
4x²(1 + 2x) - 3(1 + 2x) + 9 - x
(4x² - 3) (1 + 2x) + 9 - x

What are similar figures?This characteristic is referred to as resemblance or comparable figures when two or more items or figures appear to be the same or equal based on their shapes. These figures always superimpose one another regardless of how they are magnified or diminished. When two shapes, such triangles, polygons, or quadrilaterals, have the same dimension or common ratio but a different size or length, they are referred to as comparable figures in geometry.
Given quadrilateral's are similar
ABCD ≈ EFGH
for similarity the angles of both figures are equal and ratio of length of their sides are equal,
so AB/EF = BC/FG = CD/GH = DA/HE
we have AB = 3, EF = 2
CD = 4.5 and GH = y
substitute the values
3/2 = 4.5 /y
y = (4.5 x2)/3
y = 3 units.
Hence the measure of y is 3 units.

The table represents the distance and height for softball travels after being hit by the batter.
use a quadratic regression model to find the height of the softball when it travels 12 feet. round to the nearest foot.
The height of the softball when it travels 12 feet using the quadratic regression model is 5.53 foot.
What is the correlation coefficient?Correlation coefficient is used to calculate how strong the relationship is between the two variables.
When there is a statistical relationship between two or more variables, then they are said to be in correlation.
The table represents the distance and height for softball travels after being hit by the batter.
Distance x (ft) Height y (ft) 0 5 2 25 4 37 6 42 8 34 10 26Mean 5 28.167The mean of the data of distance is 5 and the mean of the data of height is 28.167. The correlation coefficient is 0.9938.
The quadratic regression model for this model is given as,
[tex]y=5.29+11.78x-0.98x^2[/tex]
At the 12 feet, the value of height y is,
[tex]y=5.29+11.78(12)-0.98(12)^2\\y=5.53[/tex]
Hence, the height of the softball when it travels 12 feet using the quadratic regression model is 5.53 foot.

Step-by-step explanation:

This is a lengthy question ill go through all the formulas
This is a right triangle which means u can use pythagorean theorem to find QP
formula :
[tex]a^{2} +b^{2} =c^{2}[/tex]
Note that [tex]c^{2}[/tex] is always the hypotenuse(the hyp is always opposite to ninety degrees)
so lets substitute
=> [tex]a^{2} +17^{2} =28^{2}[/tex]
=> [tex]a^{2} +289 =784[/tex]
subtract 289 both sides
[tex]= > a^{2}=495[/tex]
Now square root both
[tex]\sqrt{ a}^{2}=\sqrt{495}[/tex]
==> [tex]3\sqrt{55}[/tex] or 22.2 (answer)

Answer:
30 baloons per hourStep-by-step explanation:
Use some points on the graph:
(0, 0), (2, 60), (4, 120), (8, 240)The graph is a line passing through the origin, so this is a proportional relationship.
Standard form of such relationship is
y = kx, where k- coefficient of proportionalityUsing one of the coordinate pairs find the value of k
60 = 2kk = 60/2k = 30This is indicating the number of baloons filled per hour is 30.
Simon wants to buy some flowers He goes into a flower shop and buys 7 daffodils and 6 daisies Simon wants to know the cost of daffodils per flower Unfortunately, Simon forgot to get a receipt, however, he can remember that daisies costs 61p per flower. He can also remember that he spent £8.49 What is the cost of daffodils per flower?
Answer:
69p each
Step-by-step explanation:
well if each daisy is 61p you want to multiply that price by 6 to get total daisy price, which is £3.66 Then you take £8.49 from £3.66 to get the total price of the daffodils, which is £4.83. Then you divide the the price by the number of daffodils which is 69p. :))(

Answer:
It will experience a low tide because water is drawn away from the area between the high tides.
Explanation:
The oceans on earth bulge outwards towards the sun and moon due to gravitational pull. This building is highest when the moon and sun are in line (same plane). The coastline within this plane will experience high tides while those at the right angle will have the lowest tides.
HELP PLEASE! The perimeter is 22. How much bigger is the longest side than the shortest side?
I asked this question two hours ago, and since then, I haven't recived any help. I don't mean to sound demanding and I understand that there are millions of users here, but it seems it's been a while since someone's answered this, and I can't figure it out.
Answer:
[tex]\frac{52}{7}[/tex] [tex]units[/tex]
Step-by-step explanation:
Add up all the sides.
(2a - 3) + (3a + 1) + 2a = 7a - 2
Lets set it equal to 22 since it is the perimeter
7a - 2 = 22
add 2 both sides
7a = 24
a = [tex]\frac{24}{7}[/tex]
From the image, you can tell that 2a - 3 is the shortest side and 3a + 1 is the longest side.
(3a + 1) - (2a - 3)
Substitute [tex]\frac{24}{7}[/tex] in for a.
You should be able to get [tex]\frac{52}{7}[/tex] units.
