6. 12
7. 420x^3
10. 7
14. 1
Think: You're treating the numerator and the denom. in precisely the same way. In doing so you are NOT changing the value of the fraction, only the appearance.
Example: start with 2/3. Mult num. and den. both by 7: 14/21.
2/3 and 14/21 result in precisely the same decimal fraction, showing that the latter set of fractions is equivalent to the former set.
Answer:
135
Step-by-step explanation:
2 x 54 = 108 and .50 x 54 = 27 so 108 + 27 = 135
4x (-2s+4x^2)
is an multiplication expression
Answer: Length = 642 cm
Concept:
Here, we need to know the idea of how to find the area of a rectangle.
Area (rectangle) = l × w
l = length
w = width
Solve:
<u>Given information</u>
A = 24396 cm²
w = 38 cm
<u>Given expression</u>
A = l × w
<u>Substitute values into the expression</u>
24396 = l × (38)
<u>Divide both sides by 38</u>
24396 / 38 = l × 38 / 38

Hope this helps!! :)
