Answer:

(3x + 4)^{2}

Step-by-step explanation:

I think of a number = x

multiply by 3 = 3x (basically 3 x X)

add 4 = 3x + 4

square the result got from X x 3 + 4 =  (3x + 4)^{2}

Answer:

\large\boxed{\boxed{\underline{\underline{\maltese{\pink{\pmb{\sf{\: SOLUTION: \: \: \: \: (3x + 4)^{2}}}}}}}}}

Step-by-step explanation:

The given statement is;: 'I think of a number, multiply it by 3, add 4 & square the result.'

At first, let's take the unknown number as 'x' . (asked in the question).

So, the number we think about = x

Now, we need to multiply it by 3. So,

  • 3 * x = 3x

In the next part, we need to add 4 to it so,

  • 3x + 4

Now, by squaring the result, we'll get the expression as,

  • <u>(3x + 4)²</u>

<u>____________</u>

Hope it helps!

Use the Pythagorean Theorem to determine which of the following give the measures of the legs and hypotenuse of a right triangle
kakasveta [241]

The Pythagorean theorem states that the square of the hypotenuse is equal to  the sum of the squares of the legs:

c^2=a^2+b^2.

The hypotenuse is the side with the greatest length.

Check all options:

1. c=5, a=3, b=4:

5^2=25,\\3^2+4^2=9+16=25,\\5^2=3^2+4^2 true.

2. c=14, a=4, b=11:

14^2=196,\\4^2+11^2=16+121=137,\\14^2\neq 4^2+11^2 false.

3. c=17, a=9, b=14:

17^2=289,\\9^2+14^2=81+196=277,\\17^2\neq 9^2+14^2 false.

4. c=16, a=8, b=14:

16^2=256,\\8^2+14^2=64+196=260,\\16^2\neq 8^2+14^2 false.

5. c=17, a=8, b=15:

17^2=289,\\8^2+15^2=64+225=289,\\17^2=8^2+15^2 true.

Answer: correct options are A and E.

WILL DO ABSOLUTELY ANYTHING FOR THIS ONE HELP ASAP TIMES
Rina8888 [55]

Given:

The graph of a function y=h(x).

To find:

The interval where h(x)>0.

Solution:

From the given graph graph it is clear that, the function before x=0 and after x=3.6 lies above the x-axis. So, h(x)>0 for x and x>3.6.

The function between x=0 and x=3.6 lies below the x-axis. So, h(x) for 0.

Now,

For -1, the graph of h(x) is above the x-axis. So, h(x)>0.

For 0, the graph of h(x) is below the x-axis. So, h(x).

For 1, the graph of h(x) is below the x-axis. So, h(x).

Only for the interval -1, we get h(x)>0.

Therefore, the correct option is A.
