What is the answer for this problem in the picture

DENIUS [597]

<u>Answer:</u>

The correct answer option is $= 8 x ^ 4 y z ^ 4 \sqrt{2yz}$ .

<u>Step-by-step explanation:</u>

We are given the following expression and we are to simplify it and determine whether which of the given expressions is equivalent to it, assuming $y\geq 0$ and $z\geq 0$ :

$\sqrt { 128 x ^ 8 y ^ 3 z ^ 9 }$

Breaking the terms to get:

$\sqrt { 128 x ^ 8 y ^ 3 z ^ 9 }$ $=8\sqrt{2yz} \times x^{8\times\frac{1}{2} } \times y^{2\times \frac{1}{2} } \times z^{8\times \frac{1}{2} }$

$= 8 x ^ 4 y z ^ 4 \sqrt{2yz}$

If a rectangle has an area of 2x^2+7x+3 find the perimeter

Helen [10]

Answer:

Perimeter of the rectangle=6x+8 square units

Step-by-step explanation:

Given that area of rectangle is $2x^2+7x+3$

Area of rectangle=lw square units

$2x^2+7x+3=2x^2+x+6x+3$

$=x(2x+1)+3(2x+1)$

$=(x+3)(2x+1)$

$2x^2+7x+3=(x+3)(2x+1)$

Comparing the above equation with the given area we get

lw=(x+3)(2x+1)

Therefore length=x+3 and width=2x+1

To find the perimeter :

Perimeter of the rectangle=2(l+w) square units

$=2((x+3)+(2x+1))$

$=2(x+3+2x+1)$

$=2(3x+4)$

$=6x+8$

Therefore perimeter of the rectangle=6x+8 square units

the delivered price of leah st clairs new car is 22450. she makes a 2800 down payment and pays the balance in 36 monthly payment

Degger [83]

Answer:

Total amount paid for the Car=$24,832

Finance Charge=$2,382

Step-by-step explanation:

Down payment on the Car=$2800

Number of Monthly Installments=36

Amount Paid Per Installment=$612

Total Monthly Installment Paid=36*$612=$22032

Therefore, the Total Amount Paid for the Car=Down Payment+Total Installmental Payment=2800+22032=$24,832

Next, we determine the finance charge.

Finance Charge=Total Amount Paid for the Car - Delivered Price of the Car

=24832-22450

=$2,382

Therefore:

Total amount paid for the Car=$24,832

Finance Charge=$2,382
