20 because 70 divide by = 35
Answer:
40,885,048
Step-by-step explanation:
first find 3^12 and then find 7^9.
3^12 = 531,441
7^9 = 40,353,607
Add these together and you'll get 40,885,048.
Welcome! Hope this helps.
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:
<h2>(-3) + 4x + 2 + 2x + 2x = 8x - 1</h2>
Step-by-step explanation:
(-3) + 4x + 2 + 2x + 2x <em>combine like terms</em>
= (4x + 2x + 2x) + (-3 + 2)
= 8x - 1
