Answer:
Step-by-step explanation:
2x+(x)(3+x) multiple or foil the ()
2x+3x+x^2 combine like terms
5x+x^2 or x^2+5x
the answer would be A. because two negatives equal a positive
it would be 2/6 bc, one die, rolled twice, and landing on a 2 the first time and 6 the second time, is actually a 2/6 chance, you have 6 numbers, one die, two chances.
One US dollar equals roughly .77 British Pounds, so 950x.77=731.5.
The answer is roughly 731.50 British Pounds.

Answer:
y = - 4(x + 3)² + 7
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
From the graph (h, k ) = (- 3, 7 ), thus
y = a(x + 3)² + 7
To find a we require a point on the graph other than the vertex
Using (- 2, 3) , substitute into the equation
3 = a(- 2 + 3)² + 7
3 = a + 7 ( subtract 7 from both sides )
a = - 4
Thus
y = - 4(x + 3)² + 7 ← in vertex form
