a(2a-3(1-a))+5(a-a^2)

distribute the inner most parenthesis

a( 2a -3+3a))+5(a-a^2)

combine like terms

a(5a-3) +5(a-a^2)

distribute both sets of parenthesis

5a^2 -3a +5a-5a^2

combine like terms

5a^2-5a^2 -3a+5a

2a

Answer:

ans is 2a

Step-by-step explanation:

a[2a-3(1-a)] + 5(a-a^2)

=a{2a-3+3a] + 5a - 5a^2

=a[5a-3] + 5a - 5a^2

=5a^2 - 3a + 5a - 5a^2

=2a

A gardener uses a coordinate grid to design a new garden. The gardener uses polygon WXYZ on the grid to represent the garden. Th
ValentinkaMS [17]

Answer:

A square

36 square yard.

Step-by-step explanation:

Given the following information:

W(3,3), X(-3,3), Y(-3,-3), and Z(3,-3)

So we need to graph those vertices and connect them in order.

(please have a look at the attached photo)

From the graph, it clear that the shape of the garden is a square.  

Then, we need to calculate the length of the four sides

<u>Find the length of the side YZ. </u>

The length of side YZ  =  3 + 3  =  6 yards  because point Y and Z are on the same line y = -3 so we just need to find the distance between their x coordinate

<u>Find the length of the side WZ.</u>

The length of side WZ  =  3 + 3  =  6 yards because point W and Z are on the same line x = 3 so we just need to find the distance between their y coordinate

=> the area of the square WXYZ:

= YZ*WZ

= 6*6

= 36 square yard.

Find the difference quotient of f(x)=5x+4
Aleonysh [2.5K]
The differnce quotient is basically taking the derivitive (result will be f'(x)=5, but anyway)

here is the disffernce quotient
lim_{h\rightarrow0}\frac{f(x+h)-f(x)}{h}

so
for your equation
lim_{h\rightarrow0}\frac{(5(x+h)+4)-(5x+4)}{h}
lim_{h\rightarrow0}\frac{5x+5h+4-5x-4}{h}
lim_{h\rightarrow0}\frac{5h}{h}
h's cancel and you are left with 5
the differnce quotient is 5
