3. If the area of the rectangle is 252 square units, find x. PLEASE I REALLY NEED HELP! THANK YOU
Answer:
are or rectangle = l*b
252= (x+2) (2x+1)
252= 2x²+x+ 4x +2
2x²+5x -250=0
(x-10) (2x+25)=0
so x=10
using sum and product method

Answer:
56cm²
Step-by-step explanation:
To solve this question, find the area of the triangles separately and then add all the areas to find the total area of the kite.
Attached is the image of my work
Answer:
56 cm²
Step-by-step explanation:
The area (A) of a kite is calculated as
A = [tex]\frac{1}{2}[/tex] product of the diagonals
= [tex]\frac{1}{2}[/tex] × d₁ × d₂
d₁ = 4 + 4 = 8 and d₂ = 10 + 4 = 14
A = [tex]\frac{1}{2}[/tex] × 8 × 14 = 4 × 14 = 56 cm²

HELP!!! WILL GIVE BRAINLIEST!!!! 40 POINTS!!!!!! The agriculture department of a university works with individuals wanting to build greenhouses heated with only plastic. The department raised funding for 3,450 greenhouses. The program started with a group of 310 existing greenhouses. The number grew to 3,262 greenhouses 10 years after inception. Which equation can be used to model the relationship between the number of greenhouses outfitted depending on the number of years since the project began?
Answer:
Should be something along the lines of:
3,450 = 326x - 310
Step-by-step explanation:
First, let's start with the number of years. Assume the number of years is x. 3262 greenhouses amounts to about 326 greehouses/year. The other number was the existing greenhouses, but we want just how many greenhouses that were built, per the subtraction sign.
Hope this helps!! : )

Find the distance between the points (-1,-7) and (8,-9). The answer must be a whole number or a fully simplified radical expression do not round up
Answer:
The answer is
[tex] \sqrt{85} \: \: \: units[/tex]Step-by-step explanation:
The distance between two points can be found by using the formula
[tex]d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\ [/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(-1,-7) and (8,-9)
The distance between them is
[tex]d = \sqrt{( { - 1 - 8})^{2} + ({ - 7 + 9})^{2} } \\ = \sqrt{ ({ - 9})^{2} + {2}^{2} } \\ = \sqrt{81 + 4} [/tex]

How do you find the distance of a line segment?
Answer:
Measure the distance from one endpoint to the other.
Answer:
a line segment is a portion of a straight line which is directly connected to two given points. the given points has coordinate x and y
distance = √(x2-x1)²+(y2-y1)²
example : find distance between two points (2,6) and (3,4) ( find the length of a segment)
d = √(3-2)²+(4-6)
d=√1²+2²
d=√5
Jason has applied to be a camp counselor for the summer. The job pays $9 per hour. The equation to re
job is y = 9x, where x is the number of hours he works and y is the total amount he earns,
Mia has applied to be a lifeguard for the summer. The lifeguard job is three days a week with hours and
the table below.
Hours worked
Amount paid
Tuesday
6
$52.50
Thursday
8
$70,00
Saturday
5
$43.75
Which statement best describes the hourly rates?
O The two jobs pay the same hourly rate.
The comparison cannot be made with the information given.
O Jason's camp counselor job pays a higher hourly rate than Mia's lifeguard job.
Jason's camp counselor job pays a lower hourly rate than Mia's lifeguard job.
Answer:
The correct statement is (3).
Step-by-step explanation:
Jason's hourly pay rate as a camp counselor for the summer is:
J = $9 / hour.
The table representing Mia's pay as a lifeguard for the summer is as follows:
Days Hours worked Amount paid
Tuesday 6 $52.50
Thursday 8 $70,00
Saturday 5 $43.75
Compute Mia's hourly rate for Tuesday: [tex]\frac{\$52.50}{6}=\$8.75[/tex]
Compute Mia's hourly rate for Thursday : [tex]\frac{\$70.00}{8}=\$8.75[/tex]
Compute Mia's hourly rate for Saturday: [tex]\frac{\$43.75}{5}=\$8.75[/tex]
Thus, Mia's hourly rate as a lifeguard for the summer is,
M = $8.75 / hour
This implies that Jason's camp counselor job pays a higher hourly rate than Mia's lifeguard job.
Thus, the correct statement is (3).
Answer:
The answer is C because if u multiply 6 by 9 its 54 that's how much Jason gets for 6 hours while on the other hand Mia for six hours gets 52 dollars.

Jordan's team gained 12 yards in the first play in the 2nd play they lost 8 yards witch expression could be used to describe the total yards gained by the team
Answer:
The expression is (x + 4) yards where x yards represent the initial amount of yards had by tre team
Step-by-step explanation:
In this question, we are told to write an expression which can be used to describe the total yard gained by the team.
Now, before we can write an expression showing the yard gained by the team, we need a variable that will represent the amount of yard they had initially.
Let us represent this by x yard.
By gaining 12 yards in the first play, total amount of yards now become x + 12 yards
Now in the second play, they lost 8 yards and this translates to (x + 12)-8 = (x + 4) yards

Divide both sides by 1.5
x = 31.38 days
Find the distance between the points (5, 3) and (7,6).
Answer:
[tex]d = \sqrt{13}[/tex]
Step-by-step explanation:
Use the Distance Formula to help you determine the distance between the two following points:
-Distance Formula:
[tex]d = \sqrt{(x_{2} - x_{1})^2 + ( y_{2} - y_{1})^2}[/tex]
(where [tex](x_{1}, y_{1})[/tex] represents the first point and [tex](x_{2}, y_{2})[/tex] represents the second point)
-Apply the two following points onto that equation:
[tex]d = \sqrt{(7 - 5)^2 + (6 - 3)^2}[/tex]
[tex](x_{1}, y_{1}) = (5, 3)[/tex]
[tex](x_{2}, y_{2}) = (7, 6)[/tex]
-Solve the equation:
[tex]d = \sqrt{(7 - 5)^2 + (6 - 3)^2}[/tex]
[tex]d = \sqrt{2^2 + 3^2}[/tex]
[tex]d = \sqrt{4 + 9}[/tex]
[tex]d = \sqrt{13}[/tex]
So therefore, the distance is [tex]\sqrt{13}[/tex].
