To find the length of the wire, use the Pythagorean theorem
a^2 + b^2 = c^2
18^2 + 40^2 = c ^2
324 + 1600 = c^2
1924 = c^2
44 = c
The wire is approximately 44 feet.
10=a/2 + 7
First subtract 7 from both sides
3=a/2
Next multiple 2 on both sides, so that a is by itself
3(2)=a
A=6

Answer:
Step-by-step explanation:
Janelle expanded the expression as shown below. -4(-3x + 2/7) = -12x - 3 5/7 What errors did she make?
We are given the expression:
-4(-3x + 2/7)
Solving this expression:
Expanding the brackets
-4 × -3x + -4 × 2/7
12x - 8/7
12x - 1 1/7
