Ax^2+bx+c=0
expanded, that is the x term
in
(ax+c)(dx+e), the coefient of the b term is cd+ae
so
(2x-1)(1x+5)
the b term is (-1)(1)+(2)(5)=-1+10=9
b is 9
Answer:
I'm not sure if this is fully correct but I think it is.
Step-by-step explanation:
1)x^8
2)81y^2
3)16x^4
4)-125y^9
5)a^12b^4
6)x^32/256
7)54a^6
8)8x^10
9)-48y^4x^2
10)8192x^11y^6
11)512x^9y^3
12)-96x^14y^2
13)324m^4n^2+(n^2m/6)
14)8r^6s^10
15)6x^15y^21
I think it is 584 km cubed
U would find the distance between the each point, though since the rectangle has two pairs of congruent sides you only need to solve for two and add/multiply accordingly using p = 2l + 2w and a = lw . my phones a little broken so I can’t see the pic/solve exactly but u could use the distance formula to find the lengths of the lines. hope this helped
