X=2 I believe but I need to keep typing to make it longer
Answer:The solutions are
[0.5, - 7.5]
Step-by-step explanation:
The given quadratic equation is expressed as
x² + 7x - 4 = 0
The given quadratic equation is already in the standard form of
ax² + bx + c
The general formula for solving quadratic equations is expressed as
x = [- b ± √(b² - 4ac)]/2a
From the equation given,
a = 1
b = 7
c = - 4
Therefore,
x = [- 7 ± √(7² - 4 × 1 × - 4)]/2 × 1
x = [- 7 ± √(49 - - 16)]/2
x = [- 7 ± √65]/2
x = (- 7 + √65)/2 or x = (- 7 - √65)/2
x = (- 7 + 8.06)/2 or x = (- 7 - 8.06)/2
x = 0.5 or x = - 7.5
The answer is a. 16x+h
Since a triangle is isosceles, its both legs are the same. So, we have two sides and a hypotenuse (a, a, and h)
A midsegment length (m) of a triangle is a half of a parallel bottom leg of the triangle (a):
a = 2m
The perimeter (P) of the triangle is the sum of its sides:
P = a + a + h
It is given:
m = 4x
Since a = 2m, we have:
a = 2*4x = 8x
Therefore, the perimeter is:
P = a + a + h = 8x + 8x + h = 16x + h
