Answer:
Step-by-step explanation:
1)
2(x – 4) + 32
Multiply it out.
2 * x - 2 * 4 + 32
2x - 8 + 32
2x + 24
2)
9x + 4(x + 2) – 5
Multiply it out
9x + 4 * x + 4 * 2 - 5
9x + 4x + 8 - 5
13x + 3
Answer:
63 cm
Step-by-step explanation:
piece 1: x
piece 2: x - 18
First you would subtract 2x - 18 = 108
Second you would add 108 + 18 = 2x
Third you would divide 126 divided by 2x = 63
So that would mean x = 63
If you would like to know about how long was the rope before Chris cut it and you would like to round each length to the nearest tenth to estimate the total length of the original piece of rope, you can calculate this using the following steps:
11.36 meters = 11.4 meters
13.46 meters = 13.5 meters
11.4 + 13.5 = 24.9 meters
Result: The rope was 24.9 meters long (before Chris cut it) - rounded to the nearest tenth.
Answer:
3a²b
Step-by-step explanation:
The product of two algebraic
terms is 6a3b2. If one of the terms is
2ab, find the other term.
Let us represent
First term = a
Other term = b
a × b = 6a³b²
a = 2ab
b = ?
b = 6a³b²/a
b = 6a³b²/2ab
b = 6a³b²/2a¹b¹
b = (6 ÷ 2) × a^3 - 1 × b ^2 - 1
b = 3a²b
Therefore, the other term = 3a²b
