HELP ME PLEASE WILL MARK BRAINLIEST

Natali [406]

Answer:

y = 7, x = 7

Step-by-step explanation:

11y + 13 = 90

11y = (90 - 13)

11y = 77

y = 7

2x + 6 = 20 (because 20 is half of 40)

2x = (20 - 6)

2x = 14

x=7

Draw a model of square root of 12 using perfect squares

Shkiper50 [21]

Answer:

The answer is " $\sqrt{12}$ is not a perfect square".

Step-by-step explanation:

12 is not a perfect square because it is the natural number, and no other natural number would square the number 12, that's why it is not a perfect square.

If we calculate the square root of $\sqrt{12}$ . so, it is will give $2\sqrt{3}$ that is not a perfect square root which can be described as follows:

$\Rightarrow \sqrt{12}= \sqrt{2\times 2\times 3}$

$= \sqrt{2^2\times 3}\\\\= 2\sqrt{3}\\\\$

$\bold{\sqrt{12}}$ is not a perfect square root.

Given that f(x)= 9x^2-180, find x

hoa [83]

$9x^{2} - 180 = 0

9x^{2} = 180

Divide both sides by 9

 x^{2} = 20

Square root both sides, and you get

x = \sqrt{20} --\ \textgreater \ simplified: 2 \sqrt{5}$
