Answer:
65 square units
Step-by-step explanation:
The area of a triangle is: height times base divided by two.
So the area of one of the triangles is 10 square units.
multiply this times 4 to get the total area of the triangles
then add the area of the square which is 5 times 5
25 plus 40 = 65 square units

Answer:
Positive
Step-by-step explanation:
Since there are two x-intercepts, -2 and 2, there is a positive discriminant. If the parabola was below the x axis and opened downwards, the discriminant would be negative.
Answer:
x=6
AC = 28
Step-by-step explanation:
4x+4= AC
4x +4 = 14 + 3x -4
4x-3x= 14-4-4
x = 6
AC = 4(6) +4 = 24+4 = 28
The answer would be 90 because all you do is add the numbers ! (: pls mark me brainliest
Fist convert the equation to vertex form
y = 2(x^2 + 14x) - 8
y = 2 [(x + 7)^2 - 49] - 8
y = 2(x + 7)^2 - 106
So the vertex is at (-7,-106)
