If a right triangle has equal legs, it is by definition a 45-45-90 triangle. So, the two sides would be x and the hypotenuse would x\sqrt{2}. However, we know the hypotenuse, and we do not see a \sqrt{2} anywhere. That means it has already been multiplied by it, so to get the lengths of the sides we simply divide 26 by \sqrt{2}. If you have to rationalize the denominator, the answer will be \frac{26}{\sqrt{2}}  = \frac{26\sqrt{2}}{2}  = 13\sqrt{2}

\boxed {\text{pythagorean theorem :}a^2 + b^2 = c^2}

Let the leg be x.

x² + x² = 26²

-

Solve x:

x² + x² = 26²

<u><em>Combine like terms:</em></u>

2x² = 676

<u><em>Divide both sides by 2:</em></u>

x² = 338

<u><em>Square root both sides:</em></u>

x= √338

<u><em>Put it in radical form:</em></u>

x = 13√2

-

Answer: 13√2

Mr. Jennings is shopping for a car loan. He wants to buy a car that costs $18,000. He plans to pay $5,000 in cash and get a loan
Ugo [173]

Answer:

$650

Step-by-step explanation:

Interest = amount of the loan x interest rate x time

Amount of the loan = price of the car - cash payment

$18,000 - $5,000 = $13,000

interest rate = 5%

time = 1 year

$13,000 x 0.05 x 1 = $650

In 1996, funding for a program increased by 0.62 billion dollars from the funding in 1995. In 1997, the funding increased 0.29 b
11111nata11111 [884]
1995 = x
1996 = x + 0.62
1997 = x + 0.62 + 0.29

x + x + 0.62 + x + 0.62 + 0.29 = 11.25
3x + 1.53 = 11.25
3x = 11.25 - 1.53
3x = 9.72
x = 9.72 / 3
x = 3.24 <== 1995 = 3.24 million

1996 = 3.24 + 0.62 = 3.86 million <==
1997 = 3.24 + 0.62 + 0.29 = 4.15 million <==
