Mathematics
1 answer:
jeka57 [31]3 years ago

Answer:

x^2 + 11x + 18.

Step-by-step explanation:

The length = x + 9 and the width = x + 2.

So the area

= length * width

= (x + 9)(x + 2)

= x(x + 2) + 9(x + 2)

= x^2 + 2x + 9x + 18

= x^2 + 11x + 18.

Solve the simultaneous equations<br> y=2-5x<br> y = x² – 2x – 8
Aloiza [94]

Answer:

Step-by-step explanation:

sub equation 1 into 2

2-5x=x²-2x-8

0=x²-2x+5x-8-2

0=x²+3x-10

0=(x-2)(x+5)

x=2 or x=-5

sub x into equation 1

y=2-5(2)                            or        y=2-5(-5)

y=-8                                              y=27
