Part (a)
<h3>Answer:
2(2.4+w) = 14.2</h3>
--------------
Explanation:
L = 2.4 = length
W = unknown width
The perimeter of any rectangle is P = 2(L+W)
We replace L with 2.4, and replace P with 14.2 to get 14.2 = 2(2.4+w) which is equivalent to 2(2.4+w) = 14.2
========================================================
Part (b)
<h3>Answer:
w = 4.7</h3>
--------------
Explanation:
We'll solve the equation we set up in part (a)
2(2.4+w) = 14.2
2(2.4)+2(w) = 14.2
4.8+2w = 14.2
2w = 14.2-4.8
2w = 9.4
w = 9.4/2
w = 4.7
The width must be 4.7 cm.
It = 6.888888888 and you can round it to 7
Answer:p=69
Step-by-step explanation:
Let's solve your equation step-by-step.
3666=39(p+25)
Step 1: Simplify both sides of the equation.
3666=39(p+25)
3666=(39)(p)+(39)(25)(Distribute)
3666=39p+975
Step 2: Flip the equation.
39p+975=3666
Step 3: Subtract 975 from both sides.
39p+975−975=3666−975
39p=2691
Step 4: Divide both sides by 39.
39p
/39 = 2691
/39
