Answer:
shs92800
Step-by-step explanation:
Let the money owned by the man be x.
Hence the man gave ⅝of his money to his son;
Meaning the son gets:
⅝ × x = ⅝x
¾ of the remaining to his daughter,
Meaning his daughter gets :
¾ ×(x-⅝x) = ¾×3/8 x = 9/32X
the remaining to his wife,
Meaning his wife gets:
x-(5/8x + 9/32x) = x - 29/32x = 3/32 x
But his wife's amount is Shs8700
Meaning 3/32x = Shs8700
x= Shs8700 × 32/3 = shs92800
Answer:
9x^2 and -30x
Step-by-step explanation:
Basically, what we want to do is expand out (3x - 5)^2, which is the same as (3x - 5)(3x - 5).
Use FOIL (first, outer, inner, last):
- the first terms are 3x and 3x, so multiply those together: 3x * 3x = 9x^2
- the outer terms are 3x and -5, so multiply those: 3x * (-5) = -15x
- the inner terms are -5 and 3x, so multiply those: (-5) * 3x = -15x
- the last terms are -5 and -5, so multiply those together: (-5) * (-5) = 25
Add all these together:
9x^2 + (-15x) + (-15x) + 25
9x^2 - 30x + 25
The missing terms are thus 9x^2 and -30x.
You add the letters with numbers in front for example :
6n +5m +p -5
(The postive and negative 5 dont cancel becayse there isnt a m on the negative)
