Solve the following equation or inequality for the unknown variable. Round answer to two decimal places if necessary.

Sonbull [250]

Answer:

x = 2.7

Step-by-step explanation:

The given equation is :

$(3x)^2-10=56$

We need to solve it for x.

It can be rewrite as follows:

$9x^2-10=56$

Adding 10 to both sides,

$9x^2-10+10=56+10\\\\9x^2=66\\\\x=\sqrt{\dfrac{66}{9}}\\\\x=2.70$

So, the value of x is equal to 2.7.

san4es73 [151]

Answer:

27 ft²

Step-by-step explanation:

Hello!

We can use the formula given: $A = \pi r^2$

<h3>Solve</h3>

Plug in 3 for r and 3 for π.

$A = \pi r^2$
$A = 3(3)^2$
$A = 3(9)$
$A = 27$

The area of the circle is 27 ft².

P is a rectangle with a length 40 cm and width x cm

romanna [79]

We know that

the length of Q is 25% more than the length of p
so
length Q=1.25*40--------> 50 cm
the area of Q is 10% less than the area of p
Area Q=50*y
Area P=40*x
so
50*y=0.90*[40*x]---------> 50*y=36*x-------> x/y=50/36---> 25/18

the answer
the ratio x:y is 25:18
