Answer:
<h2>2x² - 16x + 30</h2>
Step-by-step explanation:
p(x) = 2x² - 4x
g(x) = x - 3
To find (pog)(x) replace every x in p(x) by g(x)
That's
(pog)(x) = 2(x - 3)² - 4(x - 3)
= 2( x² - 6x + 9) - 4x + 12
= 2x² - 12x + 18 - 4x + 12
<h3>= 2x² - 16x + 30</h3>
Hope this helps you
Answer:
168 in
Step-by-step explanation:
Pythagoras says:
b² + 56² = 70²
so
b² = 70² - 56²
b = √1764 = 42
so the perimeter is 70+56+42 = 168
Answer:
Hi,
Step-by-step explanation:
Using Al'Kashi theorem (law of cosines),
x²=26²+19²-2*26*19*cos(31°)
x²= 190,11870690...
So

I hope that this is not a control.
(8+2)^3 - 6
10^3 - 6
1000 - 6
= 994
I THINK this is correct
