EXPRESS THE AREA OF THE ENTIRE RECTANGLE. YOUR ANSWER SHOULD BE A POLYNOMIAL IN STANDARD FORM
Answers
Answer:
(x+7) times (x+3)
Step-by-step explanation:
Because a area of a rectangle is lw and you combine x and 3 to make x+3 and 7 and x to make x+7 and you multiply them together.
The area of the rectangle will be (x² + 10x + 21) unit².
What is mean by Rectangle?A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.
Given that;
The Length of the rectangle = x + 7
And, The width of the rectangle = x + 3
Now,
Since, The Length of the rectangle = x + 7
And, The width of the rectangle = x + 3
We know that;
The area of rectangle = Length × Width
= (x + 7) × (x + 3)
= x² + 3x + 7x + 21
= x² + 10x + 21
Thus, The area of rectangle = (x² + 10x + 21) unit²

Answer:
40ft
Step-by-step explanation:
Add up all four sides of your rectangle:
15ft + 15ft +5ft + 5ft = 40ft
You can find the other 5ft (the side that is missing) if you notice that the smaller sections are squares.
The area of the square is 9/16

find the measure of angle A
Answers
Answer:
30
Step-by-step explanation:
Right angle = 90 degrees
180-90 = 90, hence the right side of the equation.
x+37+x+67 = 90
2x + 104 = 90
2x = -14
x = -7
Plug in x.
-7+37 = 30 (angle a)
Angle a = 30
Answer:
angle A = 30 degrees
Step-by-step explanation:
*All triangles have an interior angle that adds up to 180 degrees
The triangle is the picture is a right triangle so one of the angles is 90 degrees.
First, we must figure out what "x" is:
⇒ 180 = 90 + x + 37 + x + 67
Combine like terms:
⇒ 180 = 2x + 194
Subtract 231 from both sides:
⇒ 180 - 194 = 2x + 149- 194
⇒ -14 = 2x
The divide both sides by 2:
⇒ [tex]\frac{-14}{2} + \frac{2x}{2}[/tex]
⇒ -7 = x
Now, we can figure out what angle A is by taking the equation "x + 37" and subtituting x by -7:
⇒ x + 37
⇒ -7 + 37
⇒ 30
To check out answers, take all of the eqautions in the picture and subtitute x by -7, (remember that it must add up to 180):
⇒ 90 + x + 37 + x + 67 = 180
⇒ 90 + (-7) + 37 + (-7) + 67 = 180
⇒ 180 = 180
Decide whether or not it is a function.
Answers
Answer:
Step-by-step explanation:
Yes it's a function.
You may be looking at v which produces m
You may be looking at r which also produces m.
That's fine. Two different x values (the domain) can produce the same y value. Lots of functions do that. (you'll study parabolas pretty soon and all that open up or down have two x values producing the same y value).
If you have a member of the domain producing 2 y values, that doesn't work. That would not be a function.
This example is a function.

An artical fills 1/2 of a magazine page. A corresponding photo takes up 3/8 of the article. How much of the page is taken up by the photo
Answers
Answer:
3/16
Step-by-step explanation:
If an article takes half of the page then;
1article = 1/2 of a page
3/8 of the article = x
Cross multiply
1×x = 1/2×3/8
x = 3/(2×8)
X = 3/16
Hence the photo takes 3/16 of the magazine

Ms. Hardy walks 12 meters in 24.7 seconds.
If she walks at this same rate, which of the
following is closest to the distance she will
walk in 5 minutes?
Answers
Answer:
she walks about 145.7 meters in 5 minutes
Step-by-step explanation:
Hey There!
so first we want to find the meters per second rate
to do this we do
[tex]\frac{12}{24.7} = 0.48582995951[/tex]
so the meters per second is 0.4858299591
Then we want to find how many seconds are in a 5 minutes
to do this we multiply 5 and 60
5x60=300
then we want to multiply that by the meters per second
300x 0.4858299591=145.748987854
so she walks about 145.7 meters in 5 minutes

d. 23.7
Answers
Answer:
23.7°
Step-by-step explanation:
To obtain the value of AB ; Use the cosine rule ;
Recall:
c² = a² + b² - 2ab Cos C
c² = 24² + 11² - 2*24*11 Cos75
c² = 576 + 121 - 528 * 0.2588190
c² = 697 - 136.656432
c² = 560.343568
c = sqrt(560.343568)
c = 23.6715
Hence, c = AB = 23.7°

Find the measure of angle 3=
Answers
Answer: 50°
Step-by-step explanation:
Since angle 3 is in a right triangle we can assume one angle is 90° and then the other missing angle will be 40°
Because you take 180°-140°(the angle next to it) which will equal 40°
Now every triangle must add up to 180°
so lets take the angles we have now
90° +40°=130°
now take that 130°
180°-130°=50°
Now check your work
90°+40°+50°=180°
Angle 3 is 50°
