If the width is 2 cm less than its length, the expression is this: w = L - 2.  The length then is just L.  The perimeter formula is 2L + 2w = P.  Filling in accordingly, we have 2L + 2(L-2)=52 and 2L + 2L - 4 = 52.  4L = 56 and L=14.  The width then is 12.  There you go!

Solve: −3(5+8x)−20≤−11
Tatiana [17]
-3(5 + 8x) - 20 ≤ -11  |use distributive property: a(b + c) = ab + ac

-15 - 24x - 20 ≤ -11

-35 - 24x ≤ -11    |add 35 to both sides

-24x ≤ 24      |change signs

24x ≥ -24    |divide both sides by 24

x ≥ -1

Answer:

Assuming the numerator was 1.

(6\sqrt{7}+1)/251

Step-by-step explanation:

Assuming the numerator was 1.
