What is the perimeter of a rectangle with length 12m and width 5

Answers

Answer 1
Answer: A rectangle has 4 sides, so two sides would be equal to 12-m and 2 sides would be equal to 5-m.

All you have to do is add up the sides:

12 + 12 + 5 + 5 = 34-m
Answer 2
Answer: 34m , just add 12+5+12+5 which =34

Consider the equation 6x+3y=9. Which equation, when graphed with the given equation, will form a system with infinitelymany solutions?
y+ 2x - 3
Oy+ 2x - 9
Oy - 2x+3
Oy--2x9

Answers

Answer:

y=-2x+3

Step-by-step explanation:

6x+3y=9\n \n3y=-6x+9\ny=-2x+3

step 1: subtract 6x on both sides

step 2: divide all numbers by 3 to get y by itself.

b. y = 30x + 1.25; $43.75
c. y = 30x + 1.25; $91.25
d. y = 1.25x + 30; $31.25

Answers

y = 1.25x + 30....after 3 hrs
y = 1.25(3) + 30
y = 3.75 + 30
y = 33.75

/2
; today the stock is valued at 203
/8
. We could say the stock
is performing at which of the following?

A. On par
B. Par equality
C. Below par
D. Above par

Answers

The correct answer for the question that is being presented above is this one: "C. Below par." Ten weeks ago Jerry bought stock at 211/2; today the stock is valued at 203/8. We could say the stock is performing at Below par

The stock is performing "Below par" since its current value is below the purchase price. The correct answer is option C.

To determine how the stock is performing, we compare the current value of the stock to the purchase price.

Ten weeks ago, Jerry bought the stock at 211/2, which can be written as 211.5. Today, the stock is valued at 203/8, which is equivalent to 203.375.

Comparing the purchase price (211.5) to the current value (203.375), we can see that the stock has decreased in value.

Therefore, the stock is performing "Below par" since its current value is below the purchase price.

Hence, the correct answer is option C.

Y=2x squared +4x-1 . help me

Answers

Answer:

y = 9/8   for part one of solving y in this equation .

Step-by-step explanation:

Answer:

x=  (√2y+6/2)-1

Step-by-step explanation:

Swap sides so that all variable terms are on the left hand side.

2x^2+4x−1=y

Subtract y from both sides.

2x^2+4x−1−y=0

Using quadratics formula:

x=-4±√4²-4*2(y-1)/2*2

x=  −4±2√2y+6/4

Next solve the equation by using either ± = subtraction or addition

I am using ± = addition. This means I add -4 to 2. From there I simplify equation.

x=  (√2y+6/2)-1

Not sure if this means to find x, but I think this is what it would be.

1/4x+3/8 factored by the GCF

Answers

Given:

(1)/(4)x+(3)/(8)

To find:

The factor form of given expression by the GCF.

Solution:

First we need to find the GCF of (1)/(4) and (3)/(8).

So, make denominators same.

(1)/(4)=(1* 2)/(4* 2)=(2)/(8)

Now,

GCF\left((2)/(8),(3)/(8)\right)=(1)/(8)

GCF\left((1)/(4),(3)/(8)\right)=(1)/(8)

We have,

(1)/(4)x+(3)/(8)

It can be written as

=(2)/(8)x+(3)/(8)

Taking out the GCF (1)/(8), we get

=(1)/(8)(2x+3)

Therefore, the required factor form is (1)/(8)(2x+3).
