Answer:
±2√10
Step-by-step explanation:
Given the equation 40 - x^2 = 0
Add x^2 to both sides
40 - x^2 + x^2 = 0+ x^2
40 = x^2
x^2 = 40
x = ±√40
x = ±√4 * √10
x = ±2√10
Hence the value of x is ±2√10
There are 20 students in the drama club. Next year, 5
students will leave the drama club and some students
will join. If d is the number of students who will join the
drama club, write an expression to represent the total
number of students in the drama club next year.
Answer:
27
Step-by-step explanation:
Let d = number Of drama club members
let y = number of yearbook club members
now you can write two equations, one for the total number of students, and one for the difference between them.
d + y =64
d - y = 10
to solve for d, add these two lines together (so as to remove the y’s)
2d + 0y = 74
d = 37
now substitute back into one of the formulas
d+y=64
37+y=64
subtract 37 from each side,
y = 27

The square is shown with a side length of 8 inches.
The area of a square is s^2, which can also be written as s x s, where a is the length of the side.
Area of the square would be 8 x 8 = 64 square inches.
The area of a circle is pi x r^2, where r is the radius. R is given as 3 inches.
The area of the circle is 3.14 x 3^2 = 28.26 square inches.
The shaded area is the square minus the circle.
The shaded area = 64 - 28.26 = 25.74 square inches.
The answer is 25.74 square inches.
Look at my explanation to know the answer clearly.
So, we're supposed to find the area of the shaded part.
In the problem, the shaded part is the square, and the side is 8 in.
Let's apply this formula, A = L · W or A². So, we can multiply the Length and Width to get the area.
The length is 8.
Since we don't have a width, we can use A². We can find 8 to the 2nd power to get the answer.
8 to the 2nd power is 64. How?
1. Break the exponent down.
8² ⇒ 8 × 8
2. Solve.
8 × 8 = 64
Hence, 64 is the answer. Hence, 64 is the answer. Now, we'll need to find the circumference of the circle.
The formula for that is 2 π r²
The radius is 3 in, so let's multiply 2 by 3² by 3.14.
3² × 3.14 = 28.26
Lastly, subtract 64 by 28.26.
64 - 28.25 = 25.74
Hence, your final answer is 25.74in.

Yannick and Jean are playing a guessing game with integers. Yannick wrote these clues to help Jean guess the unknown integer.
n + 6 greater-than-or-equal-to 15 and n + 5 less-than 15
What is the value of the unknown integer, n?
8
9
19
22
Answer:
I think 9 is the answer
Step-by-step explanation:
n + 6 greater-than-or-equal-to 15
n greater-than-or-equal-to 15 - 6
n greater-than-or-equal-to 9
n + 5 less-than 15
n less-than 15 -5
n = 10
So, less than 10 and greater-than-or-equal-to 9
n = 9 (I think so)
I hope this helps a little.
The solution is, the value of the unknown integer, n is, 9 is the answer.

During the annual black Friday sale,the OLX sold a price of ski boots at regular price of $245 at a discount of 40%the boots cost 96$, and expenses at 26% of the regular price, how much was the ski boots sold
Answer: $147
Step-by-step explanation:
The boots were sold at a 40% discount of the regular price of $245.
The price they were sold at is therefore:
= Price * ( 1 - discount)
= 245 * ( 1 - 40%)
= 245 * 60%
= $147

Choose the expressions that are equivalent to m∠AOB. Select all that apply.
Answer:
A, B, D, G, and H should be correct
Step-by-step explanation:
I've done the same problem and those were the answers shown
2∠DFE, DE, AB, ∠DOE, 2∠ACB are the equivalent expressions which are equivalent to m∠AOB.
What is Triangle?A triangle is a three-sided polygon that consists of three edges and three vertices.
The inscribed angle of the same arc is half of the central angle, the central angle of DE is ∠DOE and the inscribed angle of DE is ∠DFE
∠DOE=2∠DFE=∠AOB
Now we get ∠AOB=2∠ACB
The angles which are equivalent to ∠AOB are
∠AOB=2∠DFE
∠AOB=DE
∠AOB=AB
∠AOB=∠DOE
Hence, 2∠DFE, DE, AB, ∠DOE, 2∠ACB are the equivalent expressions which are equivalent to m∠AOB.

Answer:
B
Step-by-step explanation:
Hey There!
They are asking for the slope in standard form
y = mx + b
where m equals slope and b equals y intercept
the y intercept is located at point (0,-8) so b = -8
the slope is change in y over change in x
as y goes up one x goes up 1
1/1 = 1 so the slope is just x
so we can conclude that the equation is y = x - 8
