Mathematics

Answer:

12m^2 - 9m -30

Step-by-step explanation:

So rewrite the equation to this:

4m * 3m

4m * -6

5 * 3m

5 * -6

Now solve:

4m * 3m = 12m^2

4m * -6 = -24m

5 * 3m = 15m

5 * -6 = -30

Now add them together in order:

12m^2 - 24m + 15m - 30

Simplify -24m and 15m:

12m^2 - 9m -30

Thus

12m^2 - 9m -30 is the answer

Hope this helps!

Answer:

12m² - 9m - 30

Step-by-step explanation:

find the products (4m+5)(3m-6)

(4m + 5)(3m - 6) =

12m²- 24m + 15m - 30 =

12m² - 9m - 30

The water surface of a sea is 887,200 mi square what is the area rounded to the nearest thousand​
lana [24]

Answer:

887,000 is the answer.

Step-by-step explanation:

When rounding a number to the nearest thousands place, pay close attention to the value in the hundreds place. For example, given that the 2 in 200 is less than 5 in 887,200, the 7 in the thousands place will not be rounded up and the hundreds place will round down.

Points A(-2, 4), B(1, 3), C(4, -1) and D form a parallelogram. What are the coordinates of D?
Dominik [7]

Answer: The coordinates of D are Option c (1,-2)

<u>explanation: </u>

The Parallelogram is a quadrilateral whose opposite sides are equal and parallel. The location of a parallelogram on a coordinate plane is determined based on its four vertices.

A coordinate plane is a two-dimensional plane formed by the intersection of two lines one is a vertical line and the other is horizontal. The vertical line is the y-axis and horizontal line x-axis.

Four points of parallelogram ABCD are A(-2,4),B(1,3), C(4,-1), D(1,-2)

The value of y varies directly with x, and y = 343 when x = 49. find y when x = 8.
Natasha_Volkova [10]

The value of y is 56 when x = 8.

Given

y = 343 when x = 49

Value of y varies directly with x

Therefore, y ∝ x

We can write the equation with a constant 'k'

y = kx

When y = 343 and x = 49

343 = k × 49

k = 343/49

k = 7

When x = 8,

y = kx

y = 7 × 8

y = 56

The value of y is 56 when x = 8.

The total weight of a delivery truck is equal to the weight of the empty truck plus
AlexFokin [52]

The weight of the package is an illustration of a linear function

The total weight of the package is p = 8200 - T

<h3>How to determine the total weight of the package?</h3>

The given parameter is:

Weight of empty truck = 8200 lb

Represent the total weight of the truck with T, and the weight of the package with p.

So, we have:

T = 8200 + p

Make p the subject

p = 8200 - T

Hence, the total weight of the package is p = 8200 - T
