X+_=-7 and x+_=-4. Add 7 and 4 to each side to get (x+7) and (x+4). You want to FOIL these next, so (x+7)(x+4) = x^2+4x+7x+28. Now you just need to combine like terms, and BAM. There's your answer.
You should get something like x^2+11x+28 (:
The area of the trapezoid is the amount of space on it, and the value of the area is 16.5 square cm
<h3>How to determine the area?</h3>
The given parameters are:
Parallel sides = 3cm and 8 cm
Height = 3cm
The area is then calculated using:
Area = 0.5 * (Sum of parallel sides) * Height
So, we have:
Area = 0.5 * (3 + 8) * 3
Evaluate
Area = 16.5
Hence, the area of the trapezoid is 16.5 square cm

Answer:
-15.9%
Step-by-step explanation:
Opening stock = $8.18
Closing stock = $6.88
Loss = $1.30
Rate = - loss/opening stock × 100
= - 1.39/8.18 × 100
= - 15.9%
Answer:
2
Step-by-step explanation:
I infer that you are trying to ask what 4% of 50 is. 4% is equal to 4/100. 4/100 *50 = 4/2=2
