Simple question that I can't figure out how to answer somehow. Factor Completely, 3ab - 39ab

1 answer:

8 0

$\bf 3ab-39ab\implies \underline{3ab}-(\underline{3}\cdot 13)\underline{ab}\implies \underline{3ab}(1-13)\implies 3ab(-12)$

one may note that both are like-terms, thus you can simply subtract one from the other, but is only needed to be factored.

Answer:

(C * 9/5) + 32

Step-by-step explanation:

Basically, going from fahrenheit to celcius, you have to Deduct 32, then multiply by 5/9. So just reverse it, instead, you multiple it by the reciprocal, which is "9/5" then you add 32. Simple. :)

The perimeter of an isosceles trapezoid is 28 in and the ratio of lengths of its bases is 5:3. Find the lengths of the sides of

Natalka [10]

The measurements are:
b₁ = 8.4 inches; b₂ = 14 inches; leg₁ = 2.8 inches; leg₂ = 2.8 inches

Let x = length of base and leg

The formula for perimeter of isosceles trapezoid is P = b₁ + b₂ + 2(leg)
Where: b = base

   P = b₁ + b₂ + 2(leg)
   28 = 3x + 5x + 2(x)
   28 = 8x + 2x
28/10 = 10x/10
2.8 = x

Now, substitute the values:
     P = b₁ + b₂ + 2(leg)
   28 = 3(2.8) + 5(2.8) + 2(2.8)
28 = 8.4 + 14 + 5.6
28 = 28

Hence the measurements are:
b₁ = 8.4 inches; b₂ = 14 inches; leg₁ = 2.8 inches; leg₂ = 2.8 inches
