Please help me solve this I don’t understand it at all

Factored Form: y = ( x + 3 ) ( x + 5 ) ( Factor using the AC method)

X-intercepts: ( - 3, 0 ) , ( - 5 , 0) ( To find the x-intercept, substitute in 0 for y and solve for x)

Axis of symmetry: x = - 4

Vertex:  ( - 4 , - 1 ) ( Rewrite in vertex form and use this form to find the vertex) (h , k).

Domain: ( - infinite sign, infinite sign ) , { x | x E R }

Range: y>=-1

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.

55% are girls and 45% are boys : ) hope this
