Maya has read two less than four times
SashulF [63]

Answer:

2(2n - 1)  

Step-by-step explanation:

         Let x = the number of books Theo has read

   Then 4x = four times the number of books Theo has read.

And 4n - 2 = 2 less than four times the number of books Theo has read

 But 4n -2 = the number of books Maya has read

Factor the expression

4n - 2 = 2(2n - 1)

The factored expression is 2(2n - 1).

f(x) + n - move the graph n units up

f(x) - n - move the graph n units down

f(x + n) - move the graph n units to the left

f(x - n) - move the graph n units to the right

---------------------------------------------------------------------------------------

f(x)=-\dfrac{1}{5}x^2\\\\f(x+5)=-\dfrac{1}{5}(x+5)^2\\\\f(x+5)+2=-\dfrac{1}{5}(x+5)^2+2

<h3>B. Moved 2 units up and 5 units to the left.</h3>

The length of a photograph is 3cm less than twice the width. The area is 54cm^2. Find the dimensions of the photograph.
REY [17]
W= width
l= length= 2w-3

Area= length * width
A= lw
substitute l=2w-3 for l
54= (2w-3)(w)
54= 2w^2 - 3w
subtract 54 from both sides
0= 2w^2 - 3w - 54
factor the polynomial
0= (2w + 9)(w - 6)

Set each set of parentheses equal
to 0 and solve for width.

0=2w+9
-9=2w
-4.5= w NEGATIVE VALUE

0=w-6
6 cm=w

-4.5 is not the answer because it has a negative value. You cannot have a negative side of a photograph. So substitute 6 in to find length.

length= 2w-3
l= 2(6)-3
l= 12-3
l= 9 cm

CHECK:
w= 6cm
l= 9cm
Area= length * width
54= 6*9
54= 54

ANSWER: width= 6cm; length= 9cm

Hope this helps! :)

What are the dimensions
kobusy [5.1K]

Answer:

456 sq. units

Step-by-step explanation:

Formula for the area of the square:

b(base)*h(height)

b=21

h=16

21*16=336

Formula for the area of the triangle:

b*h/2

b=36-21=15

h=16

15*16/2=120

Add the two shaped together:

336+120=456

Label your answer: 456 sq. units
