Hello :
<span>f(x)=x²−18x+157
= x²-2(9)(x) +9²-9²+157
= (x-9)² </span>-9²+157
f(x) = (x-9)²+76....(<span>the vertex form of f(x) )
</span><span>Minimum value of f(x): y = 76</span>
Answer:
721
Step-by-step explanation
700 divided by 100 is 7.
So you have 7 hundred and 7 times 3 is 21.
700+21=721
Ok but don’t do that again there students need help and make the trusted teacher be any one
72 square centimeters because
<span>(12×10)−(8×6)</span>
<span>120−48</span>
<span>72</span>
So pemdas
square root of 9 means 9^(1/2) so it counts as an exponent so
9=3 times 3 so square root of 9=3
square root of 25
do pemdas so exponents before division
25=5 times 5 so
square root of 25==5 so
3/5=0.6
