2 × x × x × 3 × y × y × y<br> how do i do this?

zalisa [80]

Answer: $6x^2y^3$

Explanation:

The numbers 2 and 3 multiply to 6, so that's why the final coefficient is 6.

The x terms multiply to $x*x = x^2$

The y terms multiply to $y*y*y = y^3$

The exponent tells us how many copies of the base to multiply.

So overall, $2*x*x*3*y*y*y = 6x^2y^3$

What's 5 - the square root of x + 10 = the square root of 7 - x

Tcecarenko [31]

$\bf 5-\sqrt{x+10}=\sqrt{7-x}\impliedby \textit{squaring both sides}
\\\\\\
(5-\sqrt{x+10})^2=(\sqrt{7-x})^2
\\\\\\
(5^2)-10\sqrt{x+10}+(x+10)=7-x
\\\\\\
35-10\sqrt{x+10}+x=7-x\implies 28-10\sqrt{x+10}+2x=0
\\\\\\
2x+28=10\sqrt{x+10}\implies x+14=5\sqrt{x+10}\impliedby 
\begin{array}{llll}
squaring\ both\\
sides\ again
\end{array}
\\\\\\
$

$\bf (x^2)+28x+(14^2)=5^2(x+10)\implies x^2+28x+196=25x+250
\\\\\\
\begin{array}{lcclll}
x^2&+3x&-54&=0\\
&\uparrow &\uparrow \\
&-6+9&-6\cdot 9
\end{array} \implies (x+9)(x-6)=0\implies 
\begin{cases}
x+9=0\\
\boxed{x=-9}\\
-----\\
x-6=0\\
\boxed{x=6}
\end{cases}$

area of a Trapezium is 400 CM square the distance between the parallel side is 16 cm if one of the parallel side is 20 cm find t

aalyn [17]

Answer:

30cm

Step-by-step explanation:

area of a Trapezium = 1/2()a+b)h

a and b are the two sides

h is the height

Given

Area = 400 cm^2

a =20cm

h = 16cm

Required

Substitute

400 = 1/2(20+b))*16

800 = (20+b)*16

800/16 = 20 + b

50 = 20 + b

b = 50-20

b = 30cm

Hence the length of other side is 30cm

Analyze the linear inequalities and determine if the solution set is the shaded region above or below the boundary line.

KengaRu [80]

Hello!

If the y side is greater than the x side then it is shaded above

If the x side is greater than the y side then it is shaded below

So the answers are

above, above, below, above, below, below

Hope this helps!
