The real solution occurs when the graph intersects the x axis,
In the problem shown, the graph does not intersect the x axis, therefore it has no real solution, this means that the answer must have a complex conjugate pair
The answer is
function f has exactly two complex solutions
Step-by-step explanation:
B.
if he is just talking about the length than it is,
4(13x + 8)
of he is talking about overall length he swam than,
4(13x + 8) + 3(7x - 2)
c.
if x = 12
than
perimeter = 2l + 2b
so, after inserting the values we got,
→ 2[13(12) + 8] + 2[7(12) - 2]
→ 2 (156 + 8) + 2(84 - 2)
→ 2 × 164 + 2 × 82
→ 328 + 164
→ 492 ft. ← perimeter
and yeah, according to me
a is wrong as,
formula of perimeter = 2l + 2b or 2(l+b)
so, the answer should be,
2(13x + 8) + 2(7x - 2) or 2 [ (13x + 8) + (7x - 2)

The wide of the model should be approximately 5.194 inches
Step-by-step explanation:
You are building a scale model of a fishing boat
- The boat is 62 ft long
- The boat is 23 ft wide
- The model will be 14 in long
We need to find how wide should it be
∵ The boat is 62 feet long
∵ The model of the boat is 14 inches long
- That means 14 inches represents 62 feet
By using the ratio method
→ Actual (ft) : Model (in)
→ 62 : 14
→ 23 : x
By using cross multiplication
∵ 62 × x = 23 × 14
∴ 62 x = 322
- Divide both sides by 62 to find x
∴ x ≅ 5.194
∵ x represents the wide of the model
∴ The wide of the model is approximately 5.194 inches
The wide of the model should be approximately 5.194 inches

Answer:
This image show how to divide a given line segment into a number of equal parts by using a compass and ruler. First, draw the line AB. Secondly, draw a line above and divide into 5 equal distances to make a line AC. Third, using a compass by getting the distance of point C and B to be equal in the distance of point A and D, also getting the distance of point C to A to be equal to point B and D, then to make the Line DB. Finally divide into 5 equal parts by compass.
