Answer:
5/12
Step-by-step explanation:
to divide fractions you find the reciprocal of the 2nd number
and times both of the numbers
1/3 times 5/4
Multiply numerator and denominator.
=5/12
Answer:
In bold.
Step-by-step explanation:
a. (x+5)^2 – 3x(x+5) x+5 is common
= (x + 5)(x + 5 - 3x)
= (x + 5)(5 - 2x)
b. (x + 5)(5 - 2x) = 0
x = -5, 2.5.
2a. Area of the square = (x + 5)^2
Area of triangle AEB
= 1/2 * base * height
I am assuming that H is the centre of AB , so
Area = x*x
= x^2.
2b
6x^2 = (x + 5)^2
6x^2 = x^2 + 10x + 25
5x^2 - 10x - 25 = 0
x^2 - 2x - 5 = 0
x = [-(-2) +/- sqrt(2^2 - 4*1*-5)] / 2
x = -1.45, 3.45.
(we ignore the negative).
Answer:
$2.48
Step-by-step explanation:
He paid $20 and got $12.56 back so you subtract
20-12.56=7.44
So his total was 7.44 and he bought 3 bags so divide to find the individual price
7.44/3=2.48
So $2.48
