Answer:
-41
Step-by-step explanation:
3^3-5x9+6-29
calculate exponents 3^3=27
now write as; 27-5x9+6-29
now multiply and divide (left to right) 5x9=45
now rewrite as 27-45+6-29
now add and subtract(left to right) 27-45+6-29= -41
Answer: 1/24 or 0.0416
Step-by-step explanation:
Ok, first group x terms
f(x)=(x²+4x)-8
factor out quadratic coefient (no need but that's the step)
f(x)=1(x²+4x)-8
take 1/2 of the linear coefient and square it
4/2=2, (2)²=4
add positive and negative of it insides the parenthasees
f(x)=1(x²+4x+4-4)-8
factor perfect square
f(x)=1((x+2)²-4)-8
distribute
f(x)=1(x+2)²-4-8
f(x)=1(x+2)²-12
and, now if we wanted to find the x intercepts where f(x)=0 then
0=1(x+2)²-12
12=(x+2)²
+/-2√3=x+2
-2+/-2√3=x
x=-2+2√3 or -2-2√3
that is where the x intercept are
and completed square form is
f(x)=(x+2)²-12
Answer:
x=1
Step-by-step explanation:
5(5x+4)=45
25x+20=45
subtract 20 on each side
25x=25
divide by 25 on each side
x=1
