1023456. As it is a 7 digit number, 0 cant be put first. Hence the digit 1 goes first. and then come 0. After that, as there is no repetition allowed, we skip the number 1 and place 2. Then, we go chronologically until we have a total of 7 digits <span />

What two number multiply to -132 and add to -1
EastWind [94]

Answer:

The two numbers can be -12 and 11, or 11 and -12.

Step-by-step explanation:

xy=-132

x+y=-1

-------------

x=-1-y

(-1-y)y=-132

-y-y^2=-132

-y^2-y-(-132)=0

-y^2-y+132=0

y^2+y-132=0

factor out the trinomial,

(y-11)(y+12)=0

zero property,

y-11=0, y+12=0,

y=0+11=11,

y=0-12=-12

x+11=-1 & x+(-12)=-1

x=-1-11=-12

x=-1-(-12)=-1+12=11

13 packs a year. 6.50 (.50 comes from 1/2) since the question states that she uses 6_1/2 packs of pencils in the first “1/2” of the year we need to multiply the 6_1/2 by 2 and we get our answer.
