5,6,7 pls help.
Factorise this pls

Step-by-step explanation:

5. -3x^(2)+3xy-4xz

If you factor = -x(3x-3y+4z)

x^yz+xy^2z+xyz^2

xyz(x+y+z)

x^2y-xy^2+x^2y^2

xy(x-y+xy)

6. 14a^2-28a^2b^2+21a^4

-7a^2(4b^2-3a^2-2)

7. a^4b-6a^2b^2+3ab^3

ab(a^3-6ab+3b^2)

gregory's graph is incorrect because it shows 2 inches of growth for each week when it should show 0.75 inches of growth each week.

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
