Let width be “w", length = “l" and perimeter = p
Then l = 3w-4
Perimeter = 2(w+l)
p = 2(w+3w-4) = 2w+6w-8 = 8w-8
Perimeter is 32…
8w-8 = 32
8w = 32+8
8w = 40
w = 5
l = (3×5)-4 = 11
Check… p = 2(5+11) = 2 × 16 = 32
Ans = length is 11
Hope it helps!
Answer:Do you mean find p? If so then p+10 = 90 - 49, so p = 31°. Another possibility is in the second quadrant where p + 10 = 180 - 41 so p = 129° (The 41 comes from the first p+10, i.e. 31+10 = 41),

Step-by-step explanation:
23 - (-14) = 23 + 14 = <em><u>37</u></em>
128 - (-105) = 128 + 105 = <em><u>233</u></em>
Answer:
The expressión is:
10(a+14) = 9a
and the number is:
-140
Step-by-step explanation:
The expression is:
10(a+14) = 9a
then:
10*a + 10*14 = 9a
10a + 140 = 9a
10a - 9a = -140
a = -140
Check:
10(-140+14) = 9*140
10*-126 = 1260
