Answer:
x = 5
Step-by-step explanation:
because the log is base 2 you can remove the log by raing 2 to the power of each side:
the 2 and log2 cancel leaving:
this means we can now solve through simple algebra:
Answer:
2/3
Step-by-step explanation:
Answer:
w² +9w +20
Step-by-step explanation:
Multiply it out, collect terms, and write as descending powers of w.
(5+w)(w+4) = 5w +5·4 +w² +w·4
= w² +9w +20
Answer:
42.06 ft²
Step-by-step explanation:
2 sides = 2(2.7 ft × 3.2 ft) = 2 × 8.64 ft² = 17.28 ft²
Front + back = 2(2.1 ft × 3.2 ft) = 2 × 6.72 ft² = 13.44 ft²
Top + bottom = 2(2.1 ft × 2.7 ft) = 2 × 5.67 ft² = <u>11.34 ft²
</u>
Total area = 42.06 ft²
Answer:
All of those expressions has the same value because the value of a equation in a expression is the number after the equals sign in an expression. The main reason though is because 20/0.5=(100/10)/(5/10) and 1/0.05=(10/10)/(0.5/10)
