Answer:
x = sqrt(32)
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2+ b^2 = c^2
7^2 + x^2 = 9^2
49+x^2 = 81
Subtract 49 from each side
x^2 = 81-49
x^2 =32
Take the square root of each side
sqrt(x^2) = sqrt(32)
x = sqrt(32)
20(x+17)
20×x+20×17
20x+340
Answer:
£10,737,418.24
Step-by-step explanation:
<u>Every day amount doubles:</u>
- March 1st = 1p= 2^0 p
- March 2nd = 2*1p = 2^1 p
- March 3rd = 2*2p = 2^2 p
- ...
- March 31st = 2^30 p = 1,073,741,824 p = £10,737,418. 24
9+6=15 and 15-12=3 so this =3 the -(-6) becomes positive
Can salvage 15c+ -15c is 0 + 8 is still 0
