$(\sqrt2+1)^2+(3-\sqrt3)^2-(\sqrt5+1)^2=\\
2+2\sqrt2+9-6\sqrt3+9-(5+2\sqrt5+1)=\\
20+2\sqrt2-6\sqrt3-5-2\sqrt5-1=\\

John borrowed $ from bank for 3 years at a rate of 10%

garik1379 [7]

<h3>Given:</h3>

P= $12500
R= 10%
T= 3 years

P= Principal amount
R= Rate of interest
T= Time period

The simple interest
The total amount paid

<h3>Solution:</h3>

$\large\boxed{Formula: I= \frac{PRT}{100}}$

First, we'll have to multiply, principal amount (12500), rate (10) and time period (3).

$12500×10×3$

$=375000$

Now, we'll have to divide the amount (375000) by 100.

$\frac{375000}{100}$

I=$3750

Now, we can find the total amount paid.

$\large\boxed{A=SI+P}$

Let's substitute according to the formula.

$A=3750+12500$

A=$16250

Therefore, simple interest is $3750 and $16250 was paid in total.

Find x if y = –2. 8 – 2xy = 24 A- 1/4 B-4 C. 8 D.-4

RoseWind [281]

Given The equation -2x(-2.8)=24, we are trying to find the value of X.

The first step is to devide both sides by 2

·-x(-2.8)=12

The next step would be to distribute.

·2.8x=12

Next we devide both Sides By 2.8 to get our final answer

·X=4.28

Although your choice answers are unclear, the answer is X=4.

-I hope this is the answer you are looking for, feel free to post your questions here on brainly in the future.

Giovanni purchased 25tickets to an airshow. the cost of an adult's ticket is $14 and the child's ticket is $8. if the total cost

Masteriza [31]

Giovanni purchased 20 adult tickets and 5 child's tickets.

Step-by-step explanation:

Let,

x = Adult tickets

y = Child's tickets

According to given statement;

x+y=25 Eqn 1

One adult ticket costs $14 and one child ticket costs $8, therefore,

14x+8y=320 Eqn 2

$Multiplying\ Eqn\ 1\ by\ 8\\8(x+y=25)\\8x+8y=200\ Eqn\ 3\\Subtracting\ Eqn\ 3\ from\ Eqn\ 2\\(14x+8y)-(8x+8y)=320-200\\14x+8y-8x-8y=120\\6x=120\\Dividing\ both\ sides\ by\ 6\\\frac{6x}{6}=\frac{120}{6}\\x=20$

Putting value of x in Eqn 1;

$20+y=25\\y=25-20\\y=5$

Giovanni purchased 20 adult tickets and 5 child's tickets.
