Answer:
18 meters by 14 meters
Step-by-step explanation:
Area of rectangle is base times height (AKA length times width or however you wish to call the dimensions).
This question is a system of equations question. We can make two equations. We know that every rectangle must have 2 "lengths" and 2 "widths" (4 sides in a rectangle). Since Maria only has 64 meters of fencing, we get the equation:
2L+2W = 64
Now we know the area enclosed must be 252 so we have:
L* W = 252
Rewriting the second equation we get: [tex]W=\frac{252}{L}[/tex]
Plug this into first equation to get: [tex]2L+2\left(\frac{252}{L}\right)=64[/tex]
[tex]2L+\frac{504}{L}=64[/tex]
[tex]2L^2+504=64L[/tex] (multiply everything by L)
Solving the quadratic tells us L can be 18 or 14. Let's consider if L is 18 first by plugging 18 back into the second equation to get 18 * W = 252 which gives us W = 14. If we do the same for when L = 14, we get that W = 18.
Now you might wonder why we have 2 possible combinations, that's because in reality, it doesn't matter which one we label as length (L) or width (W).

Evaluate the function w=-5x-1 when x=-3,0, and 8.
When x = -3;
w = -5(-3) - 1
w = 15 - 1
w = 14
When x = 0;
w = -5(0) - 1
w = 0 - 1
w = -1
When x = 8;
w = -5(8) - 1
w = -40 - 1
w = -41
Best of Luck!

What is the discriminant of the quadratic equation x^2 + 2x + 6 = 0 please hurry!!!
Answer:
Step-by-step explanation:
If ax² + bx + c = 0, then the discriminant is b²-4ac
x² + 2x + 6 = 0
discriminant = 2²-4·1·6 = -20
Since the discriminant is negative, there are no real roots. There are two complex roots.

Write as a product (5c-3d)^2-9d^2
Answer:
25c^2-30cd
Step-by-step explanation:
The product of expression is,
⇒ 5c (5c - 6d)
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The expression is,
⇒ (5c - 3d)² - 9d²
Now, We can write the expression in form of product as;
⇒ (5c - 3d)² - 9d²
⇒ (5c - 3d)² - (3d)²
⇒ (5c - 3d - 3d) (5c - 3d + 3d)
⇒ (5c - 6d) (5c)
⇒ 5c (5c - 6d)
Thus, The product of expression is,
⇒ 5c (5c - 6d)

#SPJ2
is (6, 0) a coordinate, a slope, or neither
Answer:
Coordinate
Step-by-step explanation:
It is a coordinate because with slope you would need at least two ordered pairs
Answer:
A coordinate.
Step-by-step explanation:
A coordinate takes the form of ( x , y ), in which x is the horizontal, while y is the vertical.
In this case, (6 ,0) is the given coordinate, in which it displaces +6 to the right of the (0 , 0).
~
A slope will typically look like either a whole number, or the more usual fraction.

Company cuz closed at $52.93 per share with a P/E ratio of 15.17 how much were earnings per share
Answer: $3.49
Step-by-step explanation:
Earnings per share shows how much of the profit of the company every share will get.
You can use it to calcutae the P/E ratio through the following formula:
P/E ratio = Share price / Earnings per share
15.17 = 52.93 / EPS
EPS * 15.17 = 52.93
EPS = 52.93 / 15.17
= $3.49

Answer:
Step-by-step explanation:
Coordinates of the vertices of the triangle are,
M(-2, 5), N(3, 2) and L(-2, 1)
Rule for the rotation of a point (x, y) 90° counterclockwise about the origin ,
(x, y) → (-y, x)
That means coordinates of a point (x, y) becomes (-y, x) after the rotation of 90° counterclockwise about the origin.
Following this rule,
M(-2, 5) → M'(-5, -2)
N(3, 2) → N'(-2, 3)
L(-2, 1) → L'(-1, -2)
Now we can draw the image triangle M'N'L' with the help of these image points.

find the area of shaded region in given figure 14 cm and 7 cm
Given:
The radii of circles are 14 cm and 7 cm.
To find:
The area of the shaded region.
Solution:
Area of a circle is
[tex]Area=\pi r^2[/tex]
From the given figure, it is clear that
Area of shaded region = Area of larger circle - Area of smaller circle
= [tex]\pi (14)^2-\pi (7)^2[/tex]
= [tex]\dfrac{22}{7}\times 14\times 14-\dfrac{22}{7}\times 7\times 7[/tex]
= [tex]616-154[/tex]
= [tex]462[/tex]
Therefore, the area of the shaded region is 462 sq. cm.

How many times larger
is 8 x 10^4 than 8 x 10^1
Answer:
8x10^4=80,000
8x10^1=80
79,920 times larger!
Step-by-step explanation:
Hope that helps! :)
The values 8 * 10^4 is 1000 times larger than 8 * 10^1
Scientific notations are expressions written in the form A * 10^n
Given the following scientifc notations:
A = 8 x 10^4
B = 8 x 10^1
In order to know how many times larger is 8 x 10^4 than 8 x 10^1, we will take the ratio of both values as shown;
Ratio =
[tex]\frac{A}{B} = \frac{8 \times 10^4}{8 \times 10^1}\\ \frac{A}{B} = 1 \times 10^{4-1} \\ \frac{A}{B} = 10^3\\ \frac{A}{B} = 1000[/tex]
This shows that the values 8 * 10^4 are 1000 times larger than 8 * 10^1

Answer:
x=7/2
Step-by-step explanation:
first, multiply 3/4 and 5/8 into the () to get rid of them.
3/4x -3/4 = 5/4x -5/2
next, combine like terms
5/4x -3/4x = -3/4 +5/2
1/2x = -3/4 +10/4 = 7/4
divide both sides by 1/2
x= 7/2

In ∆DEF, ∠F = ∠D and EF = 4 cm and DF = 5 cm. Then find the length of DE
Answer:
DE = 4cm.
Step-by-step explanation:
The Isoscles Triangle Theorem says that:
"If two sides of a triangle are congruent, then angles opposite those sides are congruent."
The converse of this theorem is
"If angles opposite those sides are congruent, then two sides of a triangle are congruent."
Therefore, since ∠F is congruent to ∠D and are opposite sides ED and EF
while EF = 4 cm and DF = 5 cm.
DE = 4cm.
