Since Doug’s brother has double the amount of Doug we can just multiply the amount Doug has by 2.
$3,215*2 = $6,430

Step-by-step explanation:
40 - 16.83 = 23.17
She has this amount because she spent it
The numbera are 14 and 56
Answer:
the volume of the triangular prism is 1,185.6 in³
Step-by-step explanation:
To find the volume of these triangular prism, we will, first, find the area of the triangle then multiply by the length
Area of triangle =
× b×h
From the diagram ,the height of the triangle is given to be 10.4 in and the base is given to be 12 in.
We will now proceed to insert the values into the formula;
Area of triangle =
× b×h
=
× 12×10.4
=
× 124.8
=62.4
Area of triangle is 62.4 in²
From the diagram is given to be 19 in
Volume of triangular prism = area of triangular prism × l
=62.4 in² × 19 in
=1,185.6 in³
Therefore the volume of the triangular prism is 1,185.6 in³
Lets simplify this
2x^2 + 2x - 10 _< 2
4x^2 - 10 _< 2
4x^2 _< -8
x^2 _< -2
x _<1.41
on the graph plot a line, then a filled in cirlce at 1.41
