Length - 14 meters
Width - 7 meters
The length is twice the width - 7 times 2 = 14
There are four sides, two 14m and two 7m. 14 x 2 + 7 x 2 = 42
Answer:
1.4 × 10^-8
Step-by-step explanation:
The chip is 14 nanometers
14 * .000000001
.000000014
Move the decimal 8 places to the right, because we need 1 number in front of the decimal for scientific notation. The exponent will be -8 because we moved it 8 places to the right
1.4 × 10^-8
We can solve for x in by substituting 'y=15-5x' from the second one into the first equation, because in the second equation, y has no coefficient, which will make it easier to substitute.
