Answer:
the length should be 28.5 cm.
Step-by-step explanation:
i used the equation 2L+2W=P (or L+L+W+W=P)
(length + length +width + width = perimeter)
I plugged the given information into this equation so i had:
2L+(2L-14)=86
then i solved for L
(this is what that work would look like if you need it):
2L + 2(L - 14) = 86
1. distribute the 2 in 2(L-14):
2L + 2L - 28 = 86
2. combine like terms:
4L - 28 = 86
3. add 28 to both sides:
4L = 114
4. divide both sides by 4
L = 28.5
hope this helped :)
First, change the given equation to slope-intercept form:
4y = 3x + 4
y = (3/4)x + 1
Because the line we are trying to write the equation for is parallel to the above line, the new line must have the same slope (3/4).
We can then substitute (4, 0) to find the y-intercept (b):
0 = (3/4) * 4 + b
0 = 3 + b
-3 = b
Our y-intercept is -3
We can now write the whole equation:
y = (3/4)x - 3
Your final answer is y = (3/4)x - 3
Hope this helps!! Let me know if you have ANY questions.
Answer:
= 4
Step-by-step explanation:
sqrt 15 = 3.872
to approximate to the nearest whole number (integer), you take the first decimal number which is 8, since 8 is greater than 5, you will add one(1) to the whole number which is 3 to make it 4.

Step-by-step explanation:
<u>Step 1: Define</u>
6c - 1 - 4c = -49
<u>Step 2: Solve for </u><em><u>c</u></em>
- Combine like terms: 2c - 1 = -49
- Isolate <em>c</em> term: 2c = -48
- Isolate <em>c</em>: c = -24
