Answer:

The numbers are 6 and 14

Step-by-step explanation:

Say the unknown numbers are x and y

Say y = 8+x ................... eqn 1

and x + y = 20 ................ eqn 2

Then if you replace y by 8+x, eqn 1 becomes

x + 8 + x = 20

Collect the like terms

x + x = 20 - 8

2x = 12

Divide both sides by 2

x = 12/6

x = 6

Then to get y, substitute 6 for x in eqn 1, and we will have

y = 8 + 6

y = 14

Answer:

First number=6

Second number=14

Step-by-step explanation:

Let the first number be x

So the second number is x+8

So the sum of the two is

X+x+8=20

2x+8=20

2x=20-8

2x=12

X=12/2

=6

The second number will x+8

So 6+8=14

First number=6

Second number=14

Answer:

c = 41 ft

Step-by-step explanation:

To solve this problem, we can use the pythagorean theorem, which is defined by the formula a^2+b^2=c^2. We are given both the lengths of the legs, so all we need to do is to plug them both in and solve for c:

9^2+40^2 = c^2\\c^2 = 81 + 1600\\c^2 = 1681\\c = 41

This is the first option.
