Answer:
1) if we plug 2 in x, f (2)/(2-2)=100/0=undefined
2)ofcourse, when u plug -2 it makes it 0, f (-2)=0
3)the remainder being constant implies it is divisible by (x-1), 2x^2 (x-1)+4 (x-1), so ax^2=2x^2, a=2
Answer:
1.4
Step-by-step explanation:
Answer:
1) Area = 12cm²
2) x = 5cm
Surface area : 69cm²
Step-by-step explanation:
Opposites sides in a rectangle would equal the same.
so Top/bottom = 20+20=40
Front/back = 15+15=30
40+30=70cm²
94-70=24cm² for left and right side 24÷2=12cm²
2) Those lines represents what side it is equal too which also means the same.
3cm, you know that base x height = surface area so surface area ÷ height = base
15/3=5cm
x=5cm
Formula : Base x Height = One surface area
Front/Back= 15+15=30
Top/bottom = 5x3 = 15+15=30
side/side = 3x3=9
30+30+9=69cm²
Answer:
it is a^2 +b^2 =c^2
Step-by-step explanation:
you square the width and the length and add them and you get the hypotenuse
then you find the root of the hypotenuse and that is our answer
Answer
12/13
Step-by-step explanation:
1/2+1/3+1/4=?
6/12+4/12+3/12=?
13/12
Reciprocal is 12/13
