The answer is 72  (--> second choice).

I can prove it without calculator so you believe me:

6\sqrt{8}\cdot3\sqrt{2}=6\cdot3\cdot\sqrt{8}\sqrt{2}=6\cdot3\cdo\sqrt{8\cdot2}=\\= 6\cdot3\cdot\sqrt{16}=6\cdot 3\cdot 4 = 72

Simplest form of the expression -2x2(x – 5) + x(2x2 – 10x) + x is
Andrei [34K]
You first simplify the expression using PEMDAS
-2x^3-10x^2+2x^3-10x^2+x
then combine like terms,
(-2x^3+2x^3), (-10x^2-10x^2), x
cancels out^
so the answer would be -20x^2+x

A rectangular plot of farmland will be bounded on one side by a river and on the other three sides by a single-strand electric f
likoan [24]

Step-by-step explanation:

Let x be the length and y be the width of the rectangular plot.

The plot is bounded on one side by a river and on the other three sides by a single-strand electric fence. It means,

x+2y = 1500

x = 1500 - 2y ....(1)

We know that the area of a rectangular plot is given by :

A = xy ....(2)

Put the value of x from equation (1) in (2)

A=(1500-2y)y\\\\A=1500y-2y^2 .....(3)

For largest area, differentiate above area equation wrt y.

\dfrac{dA}{dy}=\dfrac{d}{dy}(1500y-2y^2)\\\\=1500-4y\\\\\text{Put}\ \dfrac{dA}{dy}=0\\\\1500-4y=0\\\\y=\dfrac{1500}{4}\\\\=375

Put the value of y in equation (1).

x = 1500-2(375)

= 750 m

Put the value of y in equation (3).

A =1500(375)-2(375)^2\\A=281250\ m^2

Hence, the largest area is 281250 m² and its dimensions are 750 m and 375 m.

Melanie got a new employer pay job through the Jones recruitment agency the job pays $52,400 per year and the agency fee is equa
Zinaida [17]

Answer:

the  amount that pay to the agency is $1,091.67

Step-by-step explanation:

The computation of the amount that pay to the agency is as follows:

= Amount paid per year ÷ number of months × 25%

= $52,400 ÷ 12 months × 25%

= $1,091.67

Hence, the  amount that pay to the agency is $1,091.67

We simply applied the above formula so that the correct amount could come

What is the area of △ABC?
kirza4 [7]
Answer:
Area = 492.4 m²

Explanation:
The area of the triangle can be calculated using the side-angle-side method as follows:
Area = 0.5 * first side * second side * sin(angle included between these two sides)

This rule is illustrated in the attached image.

Now, we have:
AB = 40 m
BC = 25 m
angle B which is the angle included between AB and BC = 80 degrees

The given angle is included between the two given sides, therefore, we can apply the above rule to get the area.
Area of triangle = 0.5*40*25*sin(80)
Area of triangle = 492.4 m²

Hope this helps :)
