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.

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
