Answer: x = 5

------------------------------------------
------------------------------------------

Explanation:

We have a right triangle as indicated by the square angle marker. Two of the sides are known: specifically the hypotenuse (13) and one of the legs (12). The other leg (x) is unknown.

We can use the Pythagorean Theorem to find x

a = 12 is one of the known legs
b = x is the unknown leg
c = 13 is the hypotenuse

Pythagorean Theorem:
a^2 + b^2 = c^2
12^2 + x^2 = 13^2
144 + x^2 = 169
144 + x^2-144 = 169-144 ... subtract 144 from both sides
x^2 = 25
sqrt(x^2) = sqrt(25)  ... apply square root to both sides
x = 5 

Side Note: Keep in mind that x can't be negative so it doesn't make sense to use the plus/minus here. We'll only stick with the positive version.

I need help. Work has to be shown but i don’t know how to do them
mote1985 [20]

Step-by-step explanation:

1.

1% of 500 is 5 so multiply 5 by 8 for one year. which is 40 so multiply that by 2.

1% of 500 = 5

5 × 8 = 40

40 × 2 = 80

2.

1% of 1000 = 10

10 × 5 = 50

50 × 3 = 150

3.

12 months = 6%

6/12 = 1 month

0.5 = 1 month

0.5 × 9 = 4.5 (the amount of interest for 9 months.)

800 × 4.5% = 36

4.

12 months = 7%

7/12 = 1 month ( i'll leave this in fraction form because of the decimal points.)

7/12 x 8 = 4.666667 or 4.7 rounded.

1200 × 4.7% = 56.40
