To convert a percent to a decimal, you divide by 100.
60% = 0.60
If x is the unknown number, the word is means equal
84 = 0.60 * x
Divide both sides by 0.60
84/0.60 = (0.60/0.60)* x = x
140 = x
5(7 + 23) because you are multiplying 7 + 23 by 5. This is a numerical expression because it has numbers and opperations. This is not an algebraic expression because there are NO variables. Hope this helps :)

Take the area of the whole shape and then subtract the area of the white part, and the shaded part's area will then be left.
(8*24)-(0.5*24*8)=96
Answer D
Answer:
We shall use the method of splitting the middle term
To factorize
3x² - 10 x + 8
We need two numbers which add to give -10 and multiply to give 3 × 8 = 24
The numbers are -6 & -4
(-6)+(-4) = -10
(-6)(-4) = 24
So we shall split -10x as -6x - 4x
We get
3x² -10x + 8
= 3x² -6x -4x+8
Taking out 3x common from first two terms & -4 from the lest two terms we get
= 3x(x-2)-4(x-2)
Taking out (x-2) common we get
= (x-2)(3x-4)
So
3x² - 10x + 8 = (x-2)(3x-4)
