The square of a binomial expands as follows:

$(a+b)^2=a^2+2ab+b^2$

Expanding all the binomials, we have

$4k^2-36k+81+k^2+4k+4=4k^2+4k+1+k^2-16k+64$

Sum like terms:

$5k^2-32k+85=5k^2-12k+65$

Simplify terms appearing on both sides:

$-32k+85=-12k+65$

Move all terms involving k to the left and all numbers to the right:

$-20k=-20$

Divide both sides by -20:

$k=1$

the volume of a rectangular pyramid is 192 cubic units. if it's dimensions are reduced to one-fourth their original lemgth. what

vekshin1

We know that
scale factor=1/4
so
volume of the smaller pyramid=[scale factor]³*volume original pyramid
volume original pyramid=192 unit³
volume of the smaller pyramid=[1/4]³*192---> (1/64)*192----> 3 units ³

the answer is

3 units³

Minimize Q=3x2+3y2, where x+y=6.

weeeeeb [17]

Answer:

$+(x + y) {}^{2} = 6 {}^{2} \\ x {}^{2} + 2xy + y {?}^{2} = 36$

$x {}^{2} + y {}^{2} = 36 - 2xy$

$q = 3(x {}^{2} + y {}^{2} )$

$q = 3(36 - 2xy) = 108 - 6xy$

The value of the expression when t-32 degrees is what degrees<br>

GaryK [48]

Complete Question:

The temperature doubled. Evaluate when t = 32 degrees.

The value of the expression when t = 32 degrees is degrees

Answer:

64 degrees

Step-by-step explanation:

Given

$t = 32$

Required

Determine the value of t when it doubles

To do this, we simply multiply the current temperature by 2.

So:

$t = 32$ becomes

$t = 32 * 2$

$t = 64$

<em>Hence, the temperature when it doubles is 64 degrees</em>
