C.
An example of this is:
a² - b²
Where both terms have an even power and there are only two terms.
Answer:
x = 72 and they are a linear pair making them supplementary angles
Step-by-step explanation:
144 + (x - 36) = 180
108 + x = 180
<u>-108 -108</u>
x = 72
the answer is A
700 x 5 = 3500
30 x 5 = 150
7 x 5 = 35
3500 + 150 +35 = 3685
700 x 200 = 140,000
30 x 200 = 6000
7 x 200 = 1400
140000 + 6000 + 1400 = 147400

= sqrt(21y) * 5*7*sqrt(y)
= sqrt(y) [ sqrt(21) * 35 ] (answer)</span>
Answer:
5×10⁻²
Step-by-step explanation:
- Move the decimal so there is one non-zero digit to the left of the decimal point.
- The number of decimal places you move will be the exponent on the 10. a. If the decimal is being moved to the right, the exponent will be negative.
b. If the decimal is being moved to the left, the exponent will be positive.
- Therefore. The answer is 5×10⁻²
