Answer:
x = 1 and x = 3.
Step-by-step explanation:
y = 2 - 8x + 6
y = 2( - 4x + 3)
y = 2(x - 3)(x - 1)
So, the x-intercepts would be at...
x-3 = 0
x = 3
and
x - 1 = 0
x = 1
Hope this helps!
From their sum, the numbers are ' x ' and ' 8 - x ' .
From their product, x(8 - x) = 80 .
When you massage and manipulate this equation into the standard
quadratic form, you have
x² - 8x + 80 = 0 .
Applying the quadratic formula to tease out the solutions of this equation,
we find that they are
<em> x = 4 + 64 i</em>
and
<em> x = 4 - 64 i</em>

Surface area for a cuboid of length, l, bredth, b and height h.
= 2*(lb + bh + lh)
for 15 by 7 by 4 1/2 = 15 by 7 by 4.5
Surface area = 2*(15*7 + 15*4.5 + 7*4.5)
= 2*(105 + 67.5 + 31.5)
=2 *(204) = 408
Surface area of box = 408 in²
