Answer:

3cm. area = L x W If the area is 9 we know 3x3 = 9 and squares side length are the same so 3x3= 9cm!

Answer:

you're right it is 3 cause a squares sides are all equal and the only number that can multiply by itself to get 9 is 3.

The length of a swimming pool is 4 feet longer than 2 times its width. If the perimeter of the pool is 128 feet, what is the wid

alexandr1967 [171]

P = 2(L + W)
P = 128
L = 2W + 4

128 = 2(2W + 4 + W)
128 = 2(3W + 4)
128 = 6W + 8
128 - 8 = 6W
120 = 6W
120/6 = W
20 = W <=== width is 20 ft

L = 2W + 4
L = 2(20) + 4
L = 40 + 4
L = 44 <=== length is 44 ft

What is the following product? sqr root 10 x sqr root 10

DENIUS [597]

Answer:

Step-by-step explanation:

Note that $\sqrt{a}$ × $\sqrt{a}$ = a

Consider the following example

$\sqrt{100}$ × $\sqrt{100}$

= 10 × 10

= 100 ← the value inside the radical, thus

$\sqrt{10}$ × $\sqrt{10}$ = 10

Subject differential equation<br>Day. Month.<br>Year. ..<br>(y-secx<br>) dx + tanxdy...o

Colt1911 [192]

$(y-\sec x)\,\mathrm dx+\tan x\,\mathrm dy=0$

Divide both side by $\mathrm dx$ and rearrange terms to get a linear ODE;

$\tan x\dfrac{\mathrm dy}{\mathrm dx}+y=\sec x$

Multiply both sides by $\cos x$ :

$\sin x\dfrac{\mathrm dy}{\mathrm dx}+\cos x\,y=1$

The left side can be condensed as the derivative of a product:

$\dfrac{\mathrm d}{\mathrm dx}(\sin x\,y)=1$

Integrate both sides, then solve for $y$ :

$\sin x\,y=x+C\implies\boxed{y(x)=x\csc x+C\csc x}$
