80*4=320-(71+80+86)=83 So 83 needs to be added.
I'm guessing it's like this
example
18=2*3*3=(2¹)(3²)
315/5=63
63/3=21
21/3=7
factored form is 3*3*5*7=(3²)(5¹)(7¹)
Answer:
b, c, and f
just divide 24/30 and youll arrive at .8! .8 is also the same as 8/10 and 80%
Step-by-step explanation:
x² + 3x + 2
x² + x + 2x + 2 because 1+2=3 and 2×1=2
By taking out common terms, we get
x(x+1)+2(x+1)
(x+1)(x+2)
Hello,
Equation is y=k(x-1)²-9
and when x=0,y=-6==>-6=k*1²-9==>k=3
y=3(x-1)²-9
when y=0, 3(x-1)²-9=0
==>(x-1-√3)(x-1+√3)=0
x-intercepts are (1+√3,0) and (1-√3,0)
Answer B.
