Answer 3

Are you sure you typed these options correctly? Because I think the last option should read -5 (instead of 5) and there's a square root sign missing in all the options?

Answer 4

What are the approximate solutions of 2x2 -x +10=0?
a.-2,2.5
b.-1.97, 2.47
c. -2.5,2
d.np solution

Answer 5

@shiraz14 yes the 1 st example is correct

Answer 6

The answer to your second question is d. Actually the solution is imaginary

Answer 7

yeap I got d too.

Answer 8

As for your first solution, I do believe that you meant to include square root signs in all the functions? Please clarify if this was included in the original question.

You're correct

Answer 17

TY I do know how to figure out alot but these few types and some graphs I'm working hard to learn

Answer 18

THe perimeter of a rectangle is 54 cm. The area of the same rectangle is 176 cm2.What are the dimensions of the rectangle ?

Answer 19

11 cm by 16 cm
8cm by 22 cm
5.5 cm by 32 cm
4cm by 44 cm

Answer 20

Let the length be x and the width be y. The perimeter is thus 2x + 2y = 54, i.e. x + y = 27cm. The area is xy = 176cm^2.

Can you then try solving these set of simultaneous equations?

Answer 21

kk going try
