The total length was 6 m.
One of the tables was 1.8 m
Subtract 1.8 from 6 to find the total length of the other two tables:
6 - 1.8 = 4.2m
The other two tables are the same size, so now divide 4.2 m by 2:
4.2 / 2 = 2.1
The other tables are 2.1 m long.
HL Theorem
Because the hypotenuse is shared between the two (they both share the same hypotenuse) and the long lengths are both marked congruent (which are both a leg).
Answer:
12. a = 2
13. 
Step-by-step explanation:
12.
6a(a + 3) = 2a(3a + 5) + 16
First, distribute 6a on the left side, and distribute 2a on the right side.
6a² + 18a = 6a² + 10a + 16
Subtract 6a² from both sides.
18a = 10a + 16
Subtract 10a from both sides.
8a = 16
Divide both sides by 8.
a = 2
13.

The LCD of 2 and 3 is 6. We multiply both sides of the equation by 6 to get rid of all denominators.



Combine like terms on the left side. Distribute the 2 on the right side.

Subtract 2x from both sides.

Divide both sides by 3.

Answer:
7%
Step-by-step explanation:
Step one:
given data
The original cost of Sam’s investment is $10,000
Sam calculated his real return to be $10,700
Required:
the interest made from the investment is
10700-10000= $700
Step two:
The ROI is a percentage that tells us the interest made
interest/investment*100
=700/10000*100
=0.07*100
= 7%
The ROI is 7%
