Answer:
The answer to your question is:
Step-by-step explanation:
a) There is no figure 0.
b) From one figure to the other there are 2 more cubes
c) Number of cubes = 3 + 2(n- 1)
where n is the number of figure
d)
Number of cubes in figure 100 = 3 + 2(100 - 1)
= 3 + 2(99)
= 3 + 198
= 201
X-45\x<-4(multiply both sides by X to remove the denominator )
X-45<-4x (collect the like terms)
-45<-4x+x
-45<-3x(divide both sides by -3
-45\-3<-3\-3x
15>x
Answer:
12- 30
36- 90
Step-by-step explanation:
if she can answer 50 in 20 mins then that means she is answering 2.5 questions in 1 min and then you must multiply 2.5 by the number of mins she has making it
12 x 2.5= 30
36 x 2.5= 90
<span>i think you mean discriminant in part A

Δ=b^2-4ac=256-4*2*3=256-24=232
it is positive so it has two answers.
Part B
you can find Δ
Δ=b^2-4ac=9-4*9*(-2)=81
x1=-3+9/18=6/18=1/3
x2=-3-9/18=-12/18=-2/3
