Answer:
[tex] 25x^2 - 30x + 9 [/tex]
Step-by-step explanation:
[tex] (5x - 3)^2 = (5x - 3)(5x - 3) = [/tex]
[tex] = (5x)(5x) + (5x)(-3) + (-3)(5x) + (-3)(-3) [/tex]
[tex] = 25x^2 - 15x - 15x + 9 [/tex]
[tex] = 25x^2 - 30x + 9 [/tex]
Answer:
25x^2-30x+9

Which of the following equations is true?
A.
(2 × 3) + (-2 × 3) = (-2 × 2) + (3 × 3)
B.
(2 ÷ 3) ÷ (3 ÷ -2) = (-2 ÷ 2) ÷ (3 ÷ 3)
C.
(-2 - 3) - (3 - 2) = (-2 - 2) - (3 - 3)
D.
(-2 × 3) × (2 × 3) = ( 3 × 2) × (3 × -2 )
Answer:
D
Step-by-step explanation:
A: (2 × 3) + (-2 × 3)= 0
(-2 × 2) + (3 × 3) = 5
B:(2 ÷ 3) ÷ (3 ÷ -2) = -0.44444444444
(-2 ÷ 2) ÷ (3 ÷ 3)= -1
C:(-2 - 3) - (3 - 2)=-6
(-2 - 2) - (3 - 3)=-4
D:(-2 × 3) × (2 × 3)=-36
( 3 × 2) × (3 × -2 )-36

Answer:
Length = 13 in
Width = 10 in
Step-by-step explanation:
Let L be the length.
Let W be te width.
From the question given above, the Lenght is 3 more that the width i.e
L = 3 + W
Next, we shall determine the width (W). This can be obtained as follow:
Length (L) = 3 + W
Width (W) = W
Area (A) = 130 in²
A = L × W
130 = (3 + W) × W
Clear bracket
130 = 3W + W²
Rearrange
W² + 3W – 130 = 0
Solving by formula method
W = –b ± √(b² – 4ac) / 2a
a = 1
b = 3
c = –130
W = –3 ± √(3² – 4 × 1 × –130) / 2 × 1
W = –3 ± √(9 + 520) / 2
W = –3 ± √(529) / 2
W = –3 ± 23 / 2
W = –3 + 23 / 2 or –3 – 23 / 2
W = 20/2 or –26/2
W = 10 or –13
Since measurement can not be negative, the width is 10 in.
Finally, we shall determine the length. This can be obtained as follow:
L = 3 + W
W = 10
L = 3 + 10
L = 13 in
SUMMARY
Length = 13 in
Width = 10 in

Step-by-step explanation:
length=3w
A=48
48=3w(w)
48=3w^2
16=w^2
W=4
48/4=12
length=12

Hallar x + y
Es de geoemtria, angulos
Answer:
1). x = 40
2). y = 20
Step-by-step explanation:
1). "4x" y "160" son ángulos de vértice, por lo que son congruentes entre sí. Entonces, "4x = 160" y luego usa álgebra para resolver "x" y "x = 40".
2). "Y" y "4x" son ángulos suplementarios, por lo que si ambos se suman, forman un ángulo de 180. Entonces, "Y + 4 (40) = 180", usando álgebra daría la respuesta "Y = 20".

She can expect to hit the bullseye 5 times.
Answer:
A. 5
Step-by-step explanation:
Regina throws 25 darts and hits the bullseye 20% of the time. So we would set up the equation as 0.20*25 (as we are looking for 20% of 25 and of means multiplication and 20% is 0.20). 0.20*5=5 so she can expect to hit the bullseye 5 times. Therefore, A is the correct answer choice.

Find the area of this trapezoid. Be sure to include the correct unit in your answer.
Answer:
A = 55 in²
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )
where h is the perpendicular height and b₁, b₁ the parallel bases
Here h = 5, b₁ = 5 and b₂ = 17 , then
A = [tex]\frac{1}{2}[/tex] × 5 × (5 + 17) = 2.5 × 22 = 55 in²
Answer: 55
Step-by-step explanation: A=a+b
2h=5+17
2·5=55

Answer:
[tex]\frac{3}{4}[/tex]
Step-by-step explanation:
Probability of rolling an even number P(A):
[tex]\frac{3}{6}[/tex] = [tex]\frac{1}{2}[/tex]
Probability of flipping tails P(B):
[tex]\frac{1}{2}[/tex]
P(A OR B) = P(A) + P(B) – P(A AND B)
[tex]\frac{1}{2}[/tex] + [tex]\frac{1}{2}[/tex] - ([tex]\frac{1}{2}[/tex] x [tex]\frac{1}{2}[/tex]) = [tex]\frac{3}{4}[/tex]

Ms. Leeper gives her sixth- and seventh-grade students a geography test to decide who will represent her class in the school geography bee. The line plots below show the results of the test for her sixth-grade class and seventh-grade class, respectively.
The data for each grade have the same interquartile range (IQR). Which of the following best compares the two test score distributions?
A - The median score of the seventh-grade class is 2 points greater than the median score of the sixth-grade class. This difference is the same as the IQR.
B - The median score of the seventh-grade class is 2 points greater than the median score of the sixth-grade class. This difference is twice as much as the IQR.
C - The median score of the seventh-grade class is 3 points greater than the median score of the sixth-grade class. This difference is the same as the IQR.
D - The median score of the seventh-grade class is 3 points greater than the median score of the sixth-grade class. This difference is twice as much as the IQR.
