Answer:
A and C
Step-by-step explanation:
for A
QT/RT=ST/QT=QS/QR
There are two QT's in this
so
(QT)^2 = RT * ST
FOR B
there is no RT twice
for C
QR/RT RS/QR
There is a QR twice
so QR^2=RT*RS
FOR D there is no RT twice
(if you have the other answers for this quiz plz give them to me lol)
Answer:
Money invested in CD account: $2000
Money Invested in Savings Bond: $4000
Step-by-step explanation:
Given
Total amount=$6000
Let
x be the amount invested in CD at 4%
And
6000-x be the remaining amount invested in savings bond at 7%
So mathematically writing
0.04x+0.07(6000-x)=360
0.04x+420-0.07x=360
-0.03x+420=360
-0.03x=360-420
-0.03x= -60
x= -60/(-0.03)
x=$2000
So the amount invested in CD is $2000.
And the amount invested in savings bond is:
=6000-x
=6000-2000
=$4000 ..
Given:
Perimeter = 18 m
The formula for the perimeter of a rectangle is:

Where:
l = lenght
w = width
In this case, we have that:
l = 2w
Therefore, we substitute the values in the formula:

And solve for w:

For the length:

Answer:
The width is 3 m
The length is 6 m
Answer:
Step-by-step explanation:
First you would make the equation
(1/2x - 1/4)(5x^2 + 6)
afterwards you would multiply like normal binomials\
5/2x^3 + 3x - 5/4x^2 - 6/4
Then simplify
5/2x^3 - 5/4x^2 + 3x - 3/2
Remember to put them in order from the most roots to the least.
