Answer:

= 3sqrt(10)

Step-by-step explanation:

The distance between two points is found by

d =sqrt( x2-x1)^2 + (y2-y1)^2)

= sqrt( 0--9)^2 +(-7--4)^2)

= sqrt( (9)^2 + (-7+4)^2)

= sqrt(9^2 + (-3)^2)

= sqrt(81+9)

= sqrt(90)

We know that sqrt(ab) = sqrt(a) sqrt(b)

= sqrt(9) sqrt(10)

= 3sqrt(10)

Answer:

-11/12

Step-by-step explanation:

$\frac{5}{8}+\frac{3}{4}=\frac{5}{8}+\frac{6}{8}=\frac{11}{8} \\ \\ -\frac{2}{3}-\frac{5}{6}=-\frac{4}{6}-\frac{5}{6}=-\frac{9}{6}=-\frac{3}{2} \\ \\ \frac{11/8}{-3/2}=\frac{22/8}{-3}=-\frac{22}{24}=-\frac{11}{12}$

Pls help ASAP will mark brainliest

wolverine [178]

Answer:

Step-by-step explanation:

Rectangular prisms have F=6 faces and E=12 edges.

By cutting one corner, we are adding 3 edges.

By cutting two corners, we are adding 2*3 = 6 edges.

Therefore the new solid has 12 + 6 = 18 edges.

A textbook store sold a combined total of 289 sociology and math textbooks in a week. The number of math textbooks sold was 65 l

erica [24]

Answer:

Contradictrion

Step-by-step explanation:

First write an equation. If the total is 289, then that goes one the right side of the =. Sociology textbooks will be x. If there were 65 less than x, it will be 65-x. Lets set it up:

x + 65 -x =289

Then combine like terms.

65 = 289

There are no values of x that make the equation true. The input is a contradiction.

Answer:

Evaluate 8P6 P 6 8 using the formula nPr=n!(n−r)! P r n = n ! ( n - r ) ! . 8!(8−6)! 8 ! ( 8 - 6 ) ! Subtract 6 6 from 8 8 . 8!(2)! 8 ! ( 2 ) ! Simplify 8!(2)! 8 !

Step-by-step explanation:

evaluate" usually means to put a value in for the variable, but you don't give us a value for p. also, it is unclear if you ...
