Answer:
16x^2+36x-10
Step-by-step explanation:
2 (4x - 1)(2x + 5)
=2(8x^2-2x+20x-5)
=2(8x^2+18x-5)
=16x^2+36x-10
The ratio of width to length in simplest form is 19 : 44
<em><u>Solution:</u></em>
Given that, A cell phone is 132 mm long and 57 mm wide
Length of cell phone = 132 mm
Width of cell phone = 57 mm
We have to find the ratio of width and length in simplest form

In ratio form, we know that,

Writing in ratio form, we get
Width : length = 19 : 44
Thus the ratio of width to length in simplest form is 19 : 44
