An integer is a natural number (1, 2, 3 ...), zero, or the negative of a natural number.
-76.15 is none of those,
Answer: NO
Answer: The correct answer is C: 6x² + x - 26 = 0
Step-by-step explanation: All the variables in the question have been identified, that is, the area, the height and the base of the triangle. The area of a triangle is defined as
Area = ½ x B x H
Area = 13,
Base = B and
Height = 6B + 1
The question states that the height is 1 more than 6 times it's base. Hence the height would be, Base x 6, plus 1, that is, 6B + 1
The area can now be expressed properly as follows,
13 = ½ x B x (6B + 1)
By cross multiplication we now have
2 x 13 = B (6B + 1)
26 = 6B² + B
Subtract 26 from both sides of the equation
6B² + B - 26 = 0
However, the answer uses x as the unknown variable. So if you use x as the base of the triangle instead of B, your answer would result in
6x² + x - 26 = 0
Answer: red dot by the 40

Answer:
x=-7.5
Step-by-step explanation:
First you distribute
1/5x + 1/4 = 1/2x + 2.5
Then you subtract 1/5x from both sides
1/4 = 0.3x + 2.5
Then you subtract 2.5 on both sides
-2.25=0.3x
You divide 0.3 on both sides to get x by itself
-7.5=x
