Please help,

Mathematics
1 answer:
ra1l [238]3 years ago
4 0

Answer:

See below.

Step-by-step explanation:

2x^2 - 2x - 12 = 0

2 is a factor so we write:

2(x^2 - x - 6) = 0

2(x - 3)(x + 2) = 0

The solutions are  x = -2 and x = 3 which means that the graph of the equation passes through the x-axis at (-2, 0) and (3, 0). The graph is a parabola  opening upwards.  Also the multiplier of 2 produces a vertical transformation (stretching) of the graph of x^2 - x - 6.

A quadrilateral has angle measures of 41 52 and 54 which is the measure of the last angle
nexus9112 [7]

Answer:

213 degrees

Step-by-step explanation:

A quadrilateral has an internal measurement of angles of 360 degrees.  Given that we have 3 measures of the angles, we simply need to find the 4th.  This can be accomplished with the following equation:

x + 52 + 54 + 41 = 360

x + 52 + 95 = 360

x + 147 = 360

x = 213

Hence, the measure of the final angle is 213 degrees.

Cheers.

Nina [5.8K]

Answer:

$546,875

Step-by-step explanation:

if the trailer brand new costs $625,000 and decreases by 12.5% you want to find 10% which is $62,500. then you want to find 5% which would be $31,250. but you want 2.5% so you need to divide $31,250 by 2 which is $15,625. add $62,500 and $15,625 together which is $78,125. then do $625,000-$78,625 which gets you $546,875.
