5*2x|x|-6=24
10*|x|-6=24
10*|x|=30
Divided both sides of the equation by 10
|x|=3
X=3 X=-3
B because there is only one negative and -63 divided by 7 equals -9. If it were -7 divided by 63 that would give you an answer in decimal form.

Formula for surface are: 2(lw+wh+lh) where l is length, w is width and h is height.
Plug in for 1 - 3
1:
2((16)6 + (6)5 + (16)5)
2(96 + 30 + 80)
2(206)
412 ft²
2:
2((13)5 + (5)6 + (13)6)
2(65 + 30 + 78)
2(173)
346 mm²
3:
2((20)4 + (4)15 + (20)15)
2(80 + 60 + 300)
2(440)
880 in²
Speed of tsunami = sqrt (9.8d) m/s where d is the depth of the ocean.
Given speed of tsunami to be 320 m/s, depth of the ocean is calculated as follows:
320=sqrt (9.8d) => 320^2 = 9.8d => d= (320^2)/9.8 = 10448.98 m
To nearest meter, d=10449 m
