i dont really know how to make a line plot/dot plot on here but, 20; 1 x 21; no x's 22; 3 x's 23; 5 x's 24; 12 x's and 25 15 x's. (or whatever you use, you dont need to use x's, remember to keep them the same size.)

Answer:
The value of m is 44
Step-by-step explanation:
We have given:
1/2 m - 3/4 n = 16
Put the value of n in the given equation
1/2m - 3/4(8)=16
Now 4 and 8 will be canceled out by the table of 4
1/2 m - 3(2)=16
1/2m - 6 = 16
Now take the L.C.M of the denominator and solve for numerator:
m-2(6)/2 = 16
m-12/2 = 16
m-12 = 16*2
m-12 = 32
Add 12 at both sides:
m-12+12 = 32+12
m= 32+12
m=44
The value of m is 44....
Answer:
Step-by-step explanation:
17 : i 12x^2(4x−3) ,
ii : 5x(x−3y) ,
iii: 5xy^2z(3x^2−5z^2)
18) since the two polynomial are equal then :
2x^3+ax^2+3x-5 = x^3+x^2-2x+a same remainder x-2 then x=2
2(2)^3+a(2)^2+3(2)-5=(2)^3+(2)^2-2(2)+a solve for a
-3a=9
a=-3
18 ) x^3+y^3 -125+15xy
x^3+y^3-(5)^3-3(x)(y)(-5) then factorize x^3+y^3
(x+y)(x^2-xy+y^2)- (5)(5)^2-3(x)(y)(-5) common factor x+y-5
(x+y-5)(x^2-xy+y^2-5^2-3xy given x+y=5
5-5( x^2-xy+y^2-25-3xy) = 0
the value of the expression equal to zero
Answer:
1 3/15 - 5/15

Hope this helps. PS the / sign is supposed to be for the fraction.
