Answer:

Step-by-step explanation:

PEMDAS

P - parentheses

E - exponets

MD - multiplication/division (left to right)

AS - addition/subtraction (left to right)

First focus on what is in the parentheses: 6+2+6x3

There are no exponents. There is multiplication, so that comes first.

6x3=18

Now we are left with: 6+2+18 which equals 26

Finally, add on what was outside the parentheses: 26 x 2

And multiply that: 26x2=52

The sum of two polynomials is 10a^2b^2-8a^2b+6ab^2-4ab+2 if one addend is -5a^2b^2+12a^2b-5 what is the other addend

spayn [35]

Answer:

The other addend is $15\cdot a^{2}\cdot b^{2}-20\cdot a^{2}\cdot b + 6\cdot a \cdot b^{2}-4\cdot a \cdot b +7$ .

Step-by-step explanation:

The other addend is determined by subtracting $-5\cdot a^{2}\cdot b^{2}+12\cdot a^{2}\cdot b-5$ from $10\cdot a^{2}\cdot b^{2}-8\cdot a^{2}\cdot b + 6\cdot a\cdot b^{2}-4\cdot a \cdot b + 2$ :

$x = 10\cdot a^{2}\cdot b^{2}-8\cdot a^{2}\cdot b + 6\cdot a \cdot b^{2}-4\cdot a \cdot b + 2 - (-5\cdot a^{2}\cdot b^{2}+12\cdot a^{2}\cdot b -5)$

$x = 10\cdot a^{2}\cdot b^{2}-8\cdot a^{2}\cdot b + 6\cdot a \cdot b^{2}-4\cdot a \cdot b +2 +5\cdot a^{2}\cdot b^{2}-12\cdot a^{2}\cdot b+5$

$x = (10\cdot a^{2}\cdot b^{2}+5\cdot a^{2}\cdot b^{2})-(8\cdot a^{2}\cdot b+12\cdot a^{2}\cdot b)+6\cdot a \cdot b^{2}-4\cdot a \cdot b +7$

$x = 15\cdot a^{2}\cdot b^{2}-20\cdot a^{2}\cdot b + 6\cdot a \cdot b^{2}-4\cdot a \cdot b +7$

The other addend is $15\cdot a^{2}\cdot b^{2}-20\cdot a^{2}\cdot b + 6\cdot a \cdot b^{2}-4\cdot a \cdot b +7$ .

If it takes a sloth 10 minutes to climb 7.5 feet what’s its climbing speed in miles per hour

qwelly [4]

Answer:

.009 miles/hour

Step-by-step explanation:

$\frac{7.5}{10}\frac{feet}{minutes} * \frac{1}{5280} \frac{miles}{feet} *\frac{60}{1}\frac{minutes}{hour}$

This is the method you should take with unit conversions in general, just set up fractions so the units cancel out, like the 7.5 feet cancels out with the feet in the 1/5280 so miles is left on top.

Answer:

√3

Step-by-step explanation:

The ratio of the short sides to the hypotenuse in an isosceles right triangle is ...

1 : 1 : √2

This means ...

p·√2 = √6

p = (√6)/(√2) = √(6/2)

p = √3
