a^2 + b^2 = c^2

Let c = hypotenuse = 2x

One of the legs = x. Let a or b = x.

I will let a = x. We can then say that b = 3.

3^2 + x^2 = (2x)^2

9 + x^2 = 4x^2

9 = 4x^2 - x^2

9 = 2x^2

9/2 = x^2

sqrt{9/2} = sqrt{x^2}

3/sqrt{2} = x

Rational denominator.

[3•sqrt{2}]/2 = x = a

Side 3 is given to be 3 feet. So, b = 3.

Hypotenuse = 2x

Hypotenuse = 2([3•sqrt{2}]/2)

Hypotenuse = 3•sqrt{2}

Understand?

The three sides are 3, [3•sqrt{2}]/2 and

3•sqrt{2}.

2. Delia and Beto left for school at the same time.
Tema [17]

<u>Answer:</u>

Beto will get to the school first.

<u>Step-by-step explanation:</u>

We are given that Delia lives 3/4 mile from school and walks at a pace of

16 minutes per mile.

So Delia takes \frac{3}{4} \times 16 = 12 minutes to reach school.

While Beto lives 3 1/2 miles from school  and bikes at a pace of 3 minutes per mile.

So Beto takes \frac{7}{2} \times 3 = 10.5 minutes to reach school.

Therefore, Beto will get to the school first.

Andre tried to solve the equation 1/4(x + 12) = 2. What was his mistake? *
Umnica [9.8K]

Answer:

x=-4

Step-by-step explanation:

x+12=8    

x=8-12

Andre did not multiple both by four to get the exact whole number. He also, didnt subtract 12 which is not possible due to it being multiplied by 1/4.
