Answer:
35/6
Step-by-step explanation:
We have, 140:24
Dividing by 4 we get 35:6
As there is no other common factor to divide with, 35:6 is the simplest form.
Answer:
Trapezium (An acute trapezium to be exact)
Step-by-step explanation:
Draw all four co-ordinates on a cartesian plane. We know these co-coordinates are the vertices (corners), so draw a line connecting all four points and observe what shape you have.
Your reasoning for why it is a trapezium can include the following points.
Trapeziums are a flat, closed shape, having 4 straight sides, with one pair of parallel sides.
We can say its an acute trapezium since the bottom two angles are unequal and both measure less than 90 degrees
Answer:
zeros: -11 , 7
Line of symmetry: x = -2
Step-by-step explanation:
y = 2x² + 8x - 154 = 2*(x² + 4x - 77) = 2*(x+11)(x-7)
y = 0
x = - 11 or x = 7
line of symmetry: x = 1/2 (-11 + 7) = -2
2x² + 8x - 154 = 2*(x² + 4x +4) - 162 = 2 * (x+2)² - 162
vertex (h , k): h = -2 , k = -162
Line of symmetry: x = -2
