Answer:
6x^3 + 29x^2 + 26x -21
Step-by-step explanation:
(2x^2 + 5x -3)(3x + 7) = 6x^3 + 14x^2 + 15x^2 + 35x - 9x -21
= 6x^3 + 29x^2 + 26x -21
A = 1/2 * b * h
A = 178.5
b = h + 4
178.5 = 1/2 * (h + 4) * h
357 = h^2 + 4h
h^2 + 4h - 357 = 0
(h - 17)(h + 21) = 0
h - 17 = 0
h = 17
h + 21 = 0
h = -21 .....not this one because it is negative
b = h + 4
b = 17 + 4
b = 21
so the height is 17 inches and the base is 21 inches <==

Hope this helps you. I apologize if it’s incorrect.
12 because if you do math and know how to if you dived 60 by 5 it would be 12
Solution:
we are given that
The difference of two numbers is equal to 0.6.
Let the numbers be x and y so we can write

Their quotient is also 0.6.
so we can write

Now solve these two equations together we get





Hence the numbers are -1.5 and -0.9
