Bill tells Matt that he has 3 kids. This means that in this item, we have three unknowns, those are the ages of the three kids. First, the product of the ages is 72.
(x)(y)(z) = 72
Also, for the sum of their ages, we have
x + y + z =?
There are three variables in the equation which means that 3 equations should also be presented to determine the ages of the three children.
100 x .4 = 40
40 x 12 = 480
The bank account would have $480 over 12 years. Hope this helps and please mark brainliest
The vertex of this parabola has coordinates (1,-1).
The axis symmetry goes trough the vertex. The equation of the axis of symmetry is x=1.
When we talk about free form shapes, it can be curve, lines or simple concave or convex polygons.
1. The shape can be closed or open.
2. The curve can cross each other, that is lines or doodled lines may intersect.
3. The free form shape consist of either lines or doodled lines, which we call an open curve.
When we talk about Geometric Shapes, it consist only of Polygons, which consist of triangles, Quadrilaterals, polygons.
1. The curve is simple closed curve.
2. It consist entirely of line segments.
3. The intersection within the curve is a point.
1: 2/7 (I think)
2: √2 −3

(Number 2 is probably difficult but the two lines underneath is where the number is supposed to be)
3: 4√10

Explanation: Simplify the radical by breaking the radicand up into a product of known factors, assuming positive real numbers.
(I hope this helps and is correct)
