The answer is: " -12x³ + 28x² " .
___________________________________________
Explanation:
___________________________________________
Note the "distributive property of multiplication" :
___________________________________________a(b+c) = ab + ac ;a(b−c) = ab − ac ;___________________________________________
So; given: " - 4x² (3x - 7) " ;

→ - 4x² (3x <span>−</span> 7) ;
= [ -4x² * 3x ] − [- 4x² * -7 ] ;

= -12x³ − (28x²) ;

= -12x³ − 28x² .

The Blackburn family has a square field where they keep their cattle. The area of the field is 40,000ft squared, and mr Blackbur

Scilla [17]

Area of a square =a^2
40000=a^2
a=200 inch

Now if u can imagine a square shape with side of 200 inch each.it makes right angles
so use pythagorean theorm

c^2=a^2+b^2
c^2=(200)^2+(200)^2
c=282.84 inch

ength of a fence is 282.84 inch

Elza [17]

Answer:

If we are to treat these as two ordered pairs, then the rate of change is 0.90625

Step-by-step explanation:

To find this, use the slope equation with the ordered pairs.

m(slope) = (y2 - y1)/(x2 - x1)

m = (11 9/16 - 9 12/16)/(12 - 10)

m = (1 13/16)/2

m = 1.8125/2

m = 0.90625

Now we know that this could be a function since we have a constant slope.
