Choose a system and make a case for why you would

Determine whether or not each expression below is a perfect square. Explain why the expression is or is not a perfect square. If it is not a perfect square, find the perfect square that seems “closest” to the given expression and show how the perfect square can be adjusted to be the given expression.

1. A(x)=x^2+6x+13

2. A(x)=2x^2+8x+14

Answers

Step-by-step explanation:

These aren't a perfect square bec. 1 st and 3rd terms must be perfect square

A(X) = X^2+6X +13 be perfect square if 13 Changed to 9

= X ^2+6X +9

A(x)= 2X^2+8X +14 be perfect square

= 4X ^2+ 8X + 16

Kimoni wants to purchase a pair of shoes that are on sale for 10% off the regular price
of $64.00. Which is the sale price of the shoes?

Answers

64 * 0.10 = 6.4
64 - 6.4 = $57.60

Answer:

the price of the pair of shoes are $57.60

Step-by-step explanation:

So you first need to find out what 10% is in $64 so your going to multiply 0.1 (10% in decimal form is 0.1 ) by 64 to get 10% of the original price.

64 * 0.1 = $6.40

so now we are going to subtract $6.40 from $64 for the sale price:

$64.00 - $6.40 = $57.60

so the sale price is $57.60

z=m-x solve for x

Answers

Answer:

x = m - z

Step-by-step explanation:

z = m - x add x to both sides

z + x = m - x + x

z + x = m subtract z from both sides

z - z + x = m - z

x = m - z

Answer:

-z + m = x

Step-by-step explanation:

z = m-x

subtract the m from both sides

z-m = -x

you can't have a negative x so multiply everything by -1

-1(z-m = -x)

-z + m = x

"Between 1750 and 1760, an intricate interlocking of circumstances set coal to rule the world, not through new discoveries of coal itself but rather through improvements in spinning and weaving machinery which made possible the massing of large numbers of spinners and weavers for large-scale production. . . . It was at the call of the master weavers and spinners of England that the steam engine was set to run the machines; then to furnish a blast so that coal might be used to cheapen the smelting of iron and steel so that more machines might be made; then to pump out the deepening mines so that more and more power to keep the machines running might be won. Steam raising was coal's first great play for power and it is the work through which it still holds its industrial supremacy. Between 1800 and 1900 coal-driven engines multiplied until . . . they were producing energy equivalent to seventy million horse-power; during the first twenty years of the twentieth century, their power-producing capacity more than doubled. So coal wrought the industrial revolution, the greatest revolution in all human history, which transformed social and economic life as radically as the geographical revolution transformed the earth's surface.Robert W.
