Answer:
True
Step-by-step explanation:
2x+5=x-3 is (-8)
This is the correct answer
Answer:

Step-by-step explanation:
We have the four thickest books from the line plot given by
Two books of
inch thick and the two books of
inch thickness.
So when the two
inch thick book is being piled on the top of a
inch thick books.
Therefore, the total thickness of the pile of books is given by :



Therefore, the thickness of the pile is
.
Use ac method
for ax²+bx+c=0 when a≠1
multiply a and c, let's call the product r
what 2 numbesr multiply to get r and add to get b
2y²+9y+9=0
2*9=18
wat 2 numbers multiply to get 18 and add to get 9
3 and 6
split it up to that
2y²+3y+6y+9=0
group
(2y²+3y)+(6y+9)=0
factor
y(2y+3)+3(2y+3)=0
undistribute
(y+3)(2y+3)=0
set to zero
y+3=0
y=-3
2y+3=0
2y=-3
y=-3/2
y=-3 and -3/2
it's factored form is (x+3)(2x+3)
The area of Victoria's poster is twice the area of Krystal's poster.
<h3>How compare the areas of two similar posters</h3>
The two areas are shown in the image attached below. Each poster represents a rectangle and the ratio between the two areas (
), no unit, is defined by the following formula:
(1)
Where:
- Width of Victoria's poster, in feet.
- Height of Victoria's poster, in feet.
- Width of Krystal's poster, in feet.
- Height of Krystal's poster, in feet.
If we know that
,
,
and
, then the ratio between the two areas is:


The area of Victoria's poster is twice the area of Krystal's poster.
