P(-5) = (-5)³ - 6(-5)² - 7(-5) + 60
p(-5) = -125 - 6(25) - (-35) + 60
p(-5) = -125 - 150 + 35 + 60
p(-5) = -275 + 95
p (-5) = -180
so is x + 5 a factor of polynomial ( NO) because when make a substitution by -5 the answer will not be 0
This is the concept of algebra, given that the length of the rectangle is 5x-2 and the width is 3x+1, the perimeter is 2(5x-2)+2(3x+1). To get the total distance Zohar needs to cut with the scissors, we substitute the value of x=4 in the expression for perimeter. Hence we shall have:
2(5x-2)+2(3x+1)
=2(5*4-2)+2(3*4+1)
=2(20-2)+2(12+1)
=2(18)+2(13)
=36+26
=62 cm
The answer is 62 cm
You'd like to think 1 is true. I wonder if it really is though. There are so many horror stories out there about people in University courses that will be paid off by a McDonald's employee. (Sorry if that's you).
Again you hope this is true, but much depends on where you are. You can have a mansion in a ghetto area and it is worth next to nothing.
I should hope so.
The 4th one is a physical relationship. If the person is driving all the time it is true. There is a positive relationship.
The last one would have a random result.
All of these or none of them could have positive results. If you treat it as a pure math question, 1 should, 2 should, 3 should, 4 should and 5 should not. This question is far too subjective to get 100%. If you say anything at all, arguing it is very worthwhile. State your case and then shut up if your marker disagrees.
To find the volume of a pyramid you must multiple length x width x height, or in this case, just the base area x height. Then divide the number you get with 3.
124 x 24.2 = 3,000.8
you then divided this number by 3
3,000.8/3 = 1,000.2
A+B: the matrix with same dimension a A and B, the element in row i and column j is: Aij+Bij
Same for A-B, but with Aij-Bij
