Well you can find the growth of desert town, by using regression. This is done by a program, like Geogebra. When I insert the data and use two variable analysis, To get a function: <span><span>y=2722.695∗<span>1.0251x
I hope this helps </span></span></span>
8. 6m + 3n
11. 8r^3 - r^2
12. 3h^2 + 8
hope this helps !

First equal the equation to f(x) or y
f(x)= (x²+x-2)÷(x²-3x-4)
To find y-intercept, x coordinates have to be 0
f(0)=(0²+0-2)÷(0²-3(0)-4)
f(0)=-2/-4
f(0)=1/2 (y-intercept)
To find x-intercept, make y=0
0=(x²+x-2)÷(x²-3x-4)
0((x²-3x-4)=(x²+x-2)
0=x²+x-2
0=(x-1)(x+2)
x-1
x-1=0
x=1
x+2=0
x=-2
The x-intercepts would be 1, -2
Hope I helped :)
The expression after factorisation is 4w⁴x² (7y⁷ + 3w⁵x⁶)
<h3>What is an Expression ?</h3>
An expression is defined as a mathematical statement consisting of variables , constants and mathematical operators.
The expression given is
28w⁴x²y⁷+12w⁹x⁸
Factors of the given expression will be the common terms in both the terms
w⁴x² is common in the variable term
The HCF of 28 and 12 is 4
4w⁴x² (7y⁷ + 3w⁵x⁶)
The expression after factorisation is 4w⁴x² (7y⁷ + 3w⁵x⁶)
