Martha has 103 and together Sandra and Martha have 170 coins.
The equation which can be used to find the length of EF is option A which is EF=
.
Given the length of base of right angled triangle is 12 and the hypotenuse be 24.
We are to find the length of EF and tell which equation can be used to find the length of EF.
We know that pythagoras theorem applies in a right angled triangle.
Pythagoras theorem says that in a right angled triangle the square of the hypotenuse is equal to the sum of square of base and perpendicular.

In this triangle we are only given base and hypotenuse and we have to find EF which is perpendicular.

EF=
=
--1
=
=
Hence the equation which can be used to find the length of Ef is option A which is EF=
.
Question is incomplete as it should include the figure also.

Answer:
x=-1.28571429
Step-by-step explanation:
Let one of the numbers be x. The other number cab then be represented as 36-x (x+36-x = 36).
The product can then be represented as y = x(36-x) or y=36x-x2
The maximum or minimum is always on the axis of symmetry which has the formula x=-b/2a.
In our case, the axis of symmetry is -36/-2, so x=18.
If one number is 18 and the 2 numbers add to 36, the other number is 18 as well.
So the 2 numbers are 18 and 18 and the maximum product is 324,
