Answer:

I do not think you can simplify it any further

Step-by-step explanation:

If you mean 15p squared - 7 q squared

Because they have different variables; p and q cannot be combined unless it is multiplication or division.

Find the difference between (-11,-11) and (-12,-8) round answer to the nearest hundredth

lisov135 [29]

Answer:

Step-by-step explanation:

The two points can be made into a right triangle with the two sides defined by two lines drawn from the two given points. Use the Pythagorean Theorem to solve for the hypotenuse, the distance between the two points. See attached graph.

6^2 + 2^2 = x^2

36 + 4 = x^2

x^2 = 40

x = 6.32

Triangle A″B″C″ is formed using the translation (x + 2, y + 0) and the dilation by a scale factor of one half from the origin. W

Dafna1 [17]

Answer:

A. segment A double prime B double prime = segment AB over 2

Step-by-step explanation:

Triangle ABC with coordinates of:

A = (-3, 3), B = (1, -3), C = (-3, -3)

Translation (x + 2, y + 0), coordinates will be:

A' = (-1, 3), B = ( 3, -3), C = (-1, -3)

Dilation by a scale factor of 1/2 from the origin, coordinates will be:

A'' = (-0.5, 1.5), B'' = (1.5, -1.5), C= (-0.5, -1.5)

Let's find the length of AB and A''B'' using distance formula

d = √(x2-x1)² + (y2 - y1)²

AB = √(1-(-3))² + (-3 -3)² = √4²+6² = √16+36 = √52 = 2√13
A''B'' = √(1.5 - (-0.5)) + (-1.5 - 1.5)² = √2²+3² = √13

We see that

AB = 2A''B''

Now the answer options:

A. segment A double prime B double prime = segment AB over 2

Correct

B. segment AB = segment A double prime B double prime over 2

Incorrect. Should be AB = A''B''*2

C. segment AB over segment A double prime B double prime = one half

Incorrect. Should be AB/A''B'' = 2

D. segment A double prime B double prime over segment AB = 2

Incorrect. Should be A''B''/AB = 1/2

xenn [34]

There are 14 floors in the building, because since Juan went up 4 floors, down 3 floors, and up one floor; so we know that he is 2 floors above from where he originally started. Once he went down 9 floors he passed the starting point and went to the bottom of the building. So, the middle must have been the 7th floor. Once I knew that I multiplied 7*2 and it got me 14. So in total there are 14 floors. I hope this helped ^^

Mon wants to make 5 lbs of the sugar syrup. How much water and how much sugar does he need… b …to make 20% syrup? Answer: lbs of

Nutka1998 [239]

Answer:

Mom would required 1 lbs of Sugar and 4 lbs of water.

Step-by-step explanation:

Given:

Amount of Sugar syrup Mom wants to make = 5 lbs

Percentile amount of syrup she needs to make = 20%

Solution:

Let amount of sugar to make 20% syrup be 'x'.

So by definition of proportion we get;

$\frac {x}{5}=\frac{20}{100}$

Now Multiplying both side by 5 we get;

$\frac {x}{5}\times5=\frac{20}{100}\times5\\\\x=1\ lbs$

So we can say that;

Amount of water = $5-1=4 \ lbs$

Hence Mom would required 1 lbs of Sugar and 4 lbs of water.
