1). Two factors of -48 => x * y = -48
=> the absolute values of the two numbers may be:
48 and 1
24 and 2
16 and 3
12 and 4
6 and 8
2). Have a differencie of 19 = > x - y = 19
That makes that the numbers be + 16 and - 3
Because (+16) * (-3) = - 48
And +16 - (-3) = +16 + 3 = 19.
3) The sum of the factors is +16 + (-3) = 16 - 3 = 13.
So the answer is the option C. 13.
Answer:
see explanation
Step-by-step explanation:
The perimeter is the sum of the 3 sides, that is
perimeter = 8 + 12 + 17 = 37 cm
To use Heron's formula for area (A)
A = 
where a, b and c are the lengths of sides and s the semi perimeter
s = 37 ÷ 2 = 18.5
let a = 8, b = 12 and c = 17, then
A = 
= 
=
≈ 43.52 cm² ( to 2 dec. places )
Answer:
x^2 - xy + 1
Step-by-step explanation:
x^2 - xy + 2x/2x
2x/2x = 1
x^2 - xy + 1
This is the furthest we can simplify this expression with the given information.
540-35x= y
540 is the amount she has minus 35 and x is the weeks she withdrawn the money and y is the answer.
