1). Two factors of -48 => x * y = -48
=> the absolute values of the two numbers may be:
48 and 1
24 and 2
16 and 3
12 and 4
6 and 8
2). Have a differencie of 19 = > x - y = 19
That makes that the numbers be + 16 and - 3
Because (+16) * (-3) = - 48
And +16 - (-3) = +16 + 3 = 19.
3) The sum of the factors is +16 + (-3) = 16 - 3 = 13.
So the answer is the option C. 13.
Answer:
It will be greater than 6 because after you multiply 9/8 * 6 you get 6.75
Step-by-step explanation:
First you would multiply 9/8 * 6
you could put 6 over one so its easier like this: 6/1
then multiply 9/8 * 6/1 which gives you 6.75 after you simplify
Answer:
52
Step-by-step explanation:
A cubical box without a top is 4 cm on each edge containing 64 identical 1 cm cubes.
We have to find the number of small cubes that actually touch the box.
Now, there are 4 layers of 16 cubes from bottom to top.
In the bottom-most layer, all the 16 small cubes will touch the bottom of the large cube.
Again, from the top three layers, only the outer small cubes will touch the sides of the large cube.
So, there are 12 small cubes in each top three layers that will touch the large cube.
Hence, in total there will be (16 + 12 ×3) = 52 small cubes that actually touch the large cube box. (Answer)
-1(7+4b) - distribute the -1 to the expression
(-1 * 7) + (-1 * 4b) — ( + and - = - )when it is multiplied
= -7 - 4b — there is no like term to added to subtracted so it will stay as like
x(x^2 - 2xy+y^2) distribute x to all
= x(x^2) - x(2xy) + x(y^2)
= x^3 - 2x^2y + xy^2 in multiplication exponent add to similar variable
No like term to connect
-5x(-3+x)
= -5x(-3) -5x(+x). (- and - is +)
= 15x -5x. similar variable x so connect the like connect like term by subtracting them
= 10x
