(xa + yb + xc) divided by 3 is your answer :) I hope this helps and please mark as brainliest, I’m trying to level up
The answer is B.
Whatever the x value is you have to add 9 to it.
Answer:
390 ft²
Step-by-step explanation:
The longer base of a trapezoid is 8 ft. The longer base of a similar trapezoid is 13 ft. The area of the smaller trapezoid is 240 ft² What is the area of the larger trapezoid?
We solve the above question using proportion
(Longer base/Area of trapezoid) smaller trapezoid = (Longer base/Area of trapezoid) bigger trapezoid
Let the the Area of the bigger trapezoid = x
Hence,
= 8ft/240ft = 13ft/x ft
Cross Multiply
8ft × x = 240ft × 13ft
x = 240ft² × 12 ft/8 ft
x = 390 ft²
The sum of the lengths of any two sides of a triangle must be greater than to the length of the third side.
x - third side
if x ≤ 16 < 17 or 16 ≤ x < 17 then
x + 16 > 17 |-16
x > 1
x ∈ (1; 16]
if 16 < 17 ≤ x then
16 + 17 > x
33 > x
x ∈ [17; 33)
Answer: x ∈ (1; 16] ∪ [17; 33) → 1 < x ≤ 16 or 17 ≤ x < 33
