You are using a^2+b^2=c^2
since c is the hypotenuse
#1 the equation would be 16^2+b^2=34^2
16^2= 256
34^2= 1156
1156-256= 900
b^2=900 (now find square root of 900)
b= 30
You are now trying to find the hypotenuse or c in this so it is simpler
#2 equation - 4^2+2^2=c^2
16+4=c^2
20=c^2
c= 4.27
The mistake Jadyn made in the long division is
- Mistake in subtraction
- the first quotient
<h3>What is long division ?</h3>
Long division refers to a way of dividing large numbers
performing the long division correctly gives
divisor dividend quotient multiplication subtraction new dividend
8 335 40 8 * 40 = 320 335 - 320 15
8 15 1 8 * 1 = 8 15 - 8 7
8 70 0.8 8 * 8 = 64 70 - 64 6
8 60 0.07 8 * 7 = 56 60 - 56 4
8 40 0.005 8 * 5 = 40 40 - 40 0
The quotient is then added as
40 + 1 + 0.8 + 0.07 + 0.005 = 41.875

Answer:
x = 0.5
Step-by-step explanation:
hope this helps!
1800 ft² = 3 pounds
[divide by 3 through]
1800 ÷ 3 = 3 ÷ 3
600ft² = 1 pound
[8400 ÷ 600 = 14; so multiply by 14 through]
600 x 14 = 1 x 14
8400ft² = 14 pounds
we need 14 pounds to cover 8400 square feet.
[Find number of 4 pounds bags needed]
14 ÷ 4 = 3.5
So we need to use 4 bags of 14 pounds of lawn seeds.
