Answer:

x = 4 and -10

Step-by-step explanation:

Given the equation

x²+6x-40= 0

The common factors to use for the factorisation are +10 and -4

x²+(10x-4x)-40=0

(x²+10x)-(4x-40) = 0

x(x+10)-4(x+10) = 0

(x-4)(x+10) = 0

x-4 =0 and x+10 = 0

x = 4 and x = -10

  • First of all, a 2 foot kangaroo is casting a 7 foot shadow.
  • Next we do 7 divided by 2 which equals 3.5.
  • Since we know the shadow is going to be 3.5x the object size we have to divide its shadow by 3.5
  • 14 divided by 3.5 is  4 so the Eucalyptus tree is 4ft long

<u><em>    Your answer=4ft </em></u>

<u><em></em></u>

Hope this helps!
