Let's assume 42391.29 is divided into x parts to get 1988.83
so, we can also write as
now, we can solve for x
we can simplify it
and we get
so,
.............Answer
Answer:
Step-by-step explanation:
(a). A = 5x( 7x - 2 ) - 3x( 2x + 4 )
(b). A = 35x² - 10x - 6x² - 12x = 29x² - 22x
<em>A = 29x² - 22x</em>
Answer:
48
Step-by-step explanation:
The standard form is (x - h)2<span> = 4p (y - k), where the focus is (h, k + p) and the directrix is y = k - p. If the </span>parabola<span> is rotated so that its vertex is (h,k) and its axis of symmetry is parallel to the x-axis, it has an </span>equation<span> of (y - k)</span>2<span> = 4p (x - h), where the focus is (h + p, k) and the directrix is x = h - p.</span>
Answer:
23/36
Step-by-step explanation:
use BODMAS
fist add 3/4+2/3
to get 17/12
then subtract 17/12-7/9
to get 23/36
