Answer:
19) ( [tex]\frac{-2}{5}[/tex])^2 = [tex]\frac{4}{25}[/tex]
20) -[tex]9^{2}[/tex] = -81
21) [tex]2^{4}[/tex] = 16
Step-by-step explanation:
The only wrong ones are
19) ( [tex]\frac{-2}{5}[/tex])^2 = [tex]\frac{4}{25}[/tex]
20) -[tex]9^{2}[/tex] = -81 ... negative is not inside a parenthesis that's why it is still negative
21) you can add another way is [tex]2^{4}[/tex] = 16
Everything else looks good. Great job!

error of David's estimate?
Answers
Answer:
18%
Step-by-step explanation:
if i am right
it would be subtract 492- 600 = -108
make this a positive value so 108
and divide it by the actual made amount
108/600 which would be 0.18 multiply this by 100 and you have 18% !!

x^2-4 = (x+2)(x-2)
H.C.F = (x+2)

Factor each expression separately.
2x + 4 becomes 2(x + 2).
x^2 - 4 becomes (x - 2)(x + 2).
The highest common factor is (x + 2).

What is the value of both these problems?

Problem 2
We have an isosceles triangle because of the two congruent sides (21 each).
The angles opposite the congruent sides are known as the base angles, and the base angles are congruent. For now, we don't know what they are. They are both x. I recommend writing 'x' onto the diagram where that missing unmarked angle is.
Then we'll use the idea that all three angles of any triangle always add to 180
x+x+38 = 180
2x+38 = 180
2x = 180-38
2x = 142
x = 142/2
x = 71
Answer: Choice A) 71=======================================================
Problem 3
We use the same ideas as the previous problem. This time the base angles are 56 degrees each. The remaining angle is x.
x+56+56 = 180
x+112 = 180
x = 180-112
x = 68

How much more lumber does Kiran need in order to make the side panels? A) LaTeX: \frac{5}{6} 5 6 feet B) LaTeX: \frac{1}{2} 1 2 feet C) LaTeX: 1\frac{5}{6} 1 5 6 feet D) LaTeX: 1\frac{1}{2} 1 1 2 feet
Answers
Answer:
A) LaTeX: \frac{5}{6} 5 6 feet
Step-by-step explanation:
Kiran has 10 1/2 feet of lumber and wants to make a bookshelf.
Kiran needs two side panels that are each 5 2/3 feet.
1 side panel = 5 2/3 feet
2 side panels =
2 × 5 2/3
2 × 17/3
= 34/3
= 11 1/3 feet
Kiran would need 11 1/3 feet of lumber.
Kiran already has 10 1/2 feet
How much more lumber does Kiran need in order to make the side panels?
This is calculated as:
11 1/3 - 10 1/2
11 - 10 + (1/3 - 1/2)
1 + ( 2 - 3/6)
1 + (-1/6)
1 - 1/6
= 5/6
Hence, Kiran need 5/6 feet more of Lumber.
En el siguiente diagrama, Midtown se encuentra exactamente a mitad de camino entre Uptown y Downtown. ¿Cuál es la distancia entre Midtown y Lower East Side?
A-2.6 km
B-1.5 km
C-2.1 km
D-90 grados
Answers
Sabemos que el ángulo de uptown es 90 y el ángulo de downtown es 90 entonces son congruentes. Si midtown es exactamente la mitad del camino de uptown a downtown entonces la distancia de uptown a midtown es exactamente igual a la distancia de midtown a downtown. Como la línea de upper west side a lower east side es una transversal de la línea uptown a downtown, sabemos que el ángulo de upper,mid,up es vertical al ángulo down,mid,lower y eso significaría que esos did ángulos son congruentes. Usando el ASA theorem (ángulo, lado, ángulo) sabemos que los dos triángulos son congruentes entonces la línea de upper a mid es igual a la de mid to lower

Find QR
QR + RS = QS
18 + x + 2x + 24 = 17
Answers
Answer:
QR = 10
Step-by-step explanation:
QR + RS = QS , substitute values
18 + x + 2x + 23 = 17 , that is
3x + 41 = 17 ( subtract 41 from both sides )
3x = - 24 ( divide both sides by 3 )
x = - 8
Thus
QR = 18 + x = 18 - 8 = 10

The total number of games played is 182.
What is permutation?The number of possible arrangements for a given set is calculated mathematically using permutation, where the arrangement's order matters.
Given that, there are 14 teams and each team plays twice with the other team.
Since each team plays every other team twice, the total number of games is nothing but the permutation of 2 out of 14 which is given by:
₁₄P₂
=14!/((14-2)!)
= (14×13×12!)/ 12!
= 14×13
=182
Hence, the total number of games played is 182.

Step 1: Define
2.4x + 4.6x = 28
Step 2: Solve for x
Combine like terms (x): 7x = 28Divide 7 on both sides: x = 4Step 3: Check
Plug in x to verify it's a solution.
Substitute in x: 2.4(4) + 4.6(4) = 28Multiply: 9.6+ 18.4= 28Add: 28 = 28Here we see that 28 does indeed equal 28.
