We can use the Pythagorean theorem:
c² = a² + b²
In this case:
6² = 3² + 4²
36 = 9 + 16
36 = 25 ( not correct )
This is not a right triangle.
Answer:
B ) The triangle in question is not a right triangle.
I was Thinking it out on my art pad
A=(1/2)
bh A=(1/2)*10*12
A=5*12=60 sq cm
4*60=240 sq cm
A=s*s A=10*10=100 sq cm
240+100=340 sq cm
so A
Answer:
I need to see the choices for it
Step-by-step explanation:
Answer:
Step-by-step explanation:
f(x) = 2x² + 14x - 4
= 2(x² + 7x) - 4
= 2(x² +7x + 3.5²) - 2(3.5²) - 4
= 2(x+3.5)² - 28.5
vertex (3.5, -28.5) = (7/2, -57/2)
The vertical intercept is the y-intercept, i.e., f(0) = -4.
The x-intercepts are the values of x for which y=0.
2x² + 14x - 4 = 0
x = [-14±√(14²-4(2)(-4))]/[2(2)] = [-7±√57]/2 ≅ -7.27, 0.27
