= 3v^2 x^27

Step-by-step explanation:

Apply exponent rule: aa = a^2

VV = V^2

=3V^2x^24x^3

Simplify x^24 x^3 : x^27

= 3v^2 x^27

Which statement is true about the extreme value of the given quadratic equation?

ICE Princess25 [194]

Answer:

Option B. The equation has a maximum value with a y-coordinate of -21.

Step-by-step explanation:

The correct quadratic equation is

$y=-3x^{2}+12x-33$

This is a vertical parabola open downward (the leading coefficient is negative)

The vertex represent a maximum

Convert to vertex form

Factor -3

$y=-3(x^{2}-4x)-33$

Complete the square

$y=-3(x^{2}-4x+2^2)-33+12$

$y=-3(x^{2}-4x+4)-21$

Rewrite as perfect squares

$y=-3(x-2)^{2}-21$

The vertex is the point (2,-21)

therefore

The equation has a maximum value with a y-coordinate of -21

How much greater is the area of a a square with a side length of 8 inches than the area of a circle with radius of 4 inches?

expeople1 [14]

Area of a square= l²
= 8×8 = 64 in²

Area of a circle= πr²
= π × 4²
= 50.3 in²
Difference = 64 - 50.3 = 13.7 in²

Answer:

Step-by-step explanation:

This means that 12/(2x+1)=8/(x+4). Cross multiply to get 16x + 8 = 12x + 48. Subtract 12x + 8 from both sides to get 4x = 40, so x = 10.

2x + 5y= 18 4x + 20y= -36 Solve and Explain first to get right gets brainliest

Jet001 [13]

because 4x+20y=-36,so ( 4x+20y)/2=2x+10y=-18

(2x+10y)-(2x+5y)=-18-18

5y=-36

then y=-7.2

because 2x=18-5y

so x=(18-5y)/2=(18-5*(-7.2)）/2=27
