Answer:

(x + 5)2 + 2 = 42.5

List of steps

2(x)+2(5)

2x+10

2x+10+2=42.5

2x+12=42.5

2x=42.5-12

2x=30.5

2x/2=30.5/2

x=30.5/2

x=15.25

x=15.25

Step-by-step explanation:

(x + 5)2 + 2 = 42.5

Solve (x+5)2 first

2(x)+2(5)

2x+10

Now the equation

2x+10+2=42.5

2x+12=42.5

Make 2x the subject

2x=42.5-12

2x=30.5

Divide both sides of the equation by 2

2x/2=30.5/2

x=30.5/2

x=15.25

I’ll teach you how to solve 2(x+2)^2 -5=93
———————————————
2(x+2)^2 -5=93
Expand the expression:
2(x^2+4x+4)-5=93
Multiply the parentheses by 2:
2x^2+8x+8-5=93
Subtract the numbers:
2x^2+8x+3-5=93
Move the constant to the left;
2x^2+8x+3-93=0
Calculate:
2x^2+8x-90=0
Divide both sides by 2:
X^2+4x-45=0
Write as a difference:
X^2+9x-5x-45=0
Factor the expressions:
X•(x+9)-5(x+9)=0
Factor the expression:
(X+9)•(x-5)=0
Separate into possible cases:
X+9=0
X-5=0
Solve the equations:
X= -9
X= 5
X= -9, x= 5
Your Answer Is x= -9, x= 5

The following table shows the probability of rolling the numbers 1 through 7
Marysya12 [62]

Answer:

2.0

Step-by-step explanation:

Couldn't really understnd what you wrote but I'll assume it's the standard deviation of a fair, 7-sided die

The standard deviation is just the square root of the variance (which is just the second moment minus the first moment squared)

The first moment (AKA the average is..)

\frac{1+2+3+4+5+6+7}{7}=4

The second moment is..

\frac{1^2+2^2+3^2+4^2+5^2+6^2+7^2}{7}=20

\sqrt{20-4^2}=2

A pool is being drained at a rate of 120 gallons per minute.What is this rate in quarts per hour?
zysi [14]
There are 4 quarts in 1 gallon, so a rate of 120 gallons per minute converts to 4 x 120 = 480 quarts per minute. To find the per hour rate, we simply multiply our per minute rate by 60, obtaining 480 x 60 = 28800 quarts per hour.

A train leaves at 14:56 and arrives at 16:43. It travelled at an average speed of 135 km/h. How far did it travel? Give your ans
Firlakuza [10]

Answer:

240.8

Step-by-step explanation:

→ Calculate time taken

16:43 - 14:56 = 1 hour and 47 minutes

→ Write the speed formula and make distance the subject

Speed = Distance ÷ Time ⇔ Distance = Speed × Time

→ Convert 1 hour and 47 minutes into decimal format

1.78333333 or  1\frac{47}{60}

→ Substitute values into formula

135 ×  1\frac{47}{60}  = 240.75
