HELP ME PLEASE I HAVE BEEN DOING THIS FOR TWO HOURS, I BEG OF YOU‍♀️‍♀️

BabaBlast [244]

Answer:

The first factor is itself the sum of two terms
The solution is the product of two factors

Step-by-step explanation:

The math symbols of the expression include parentheses, a plus sign, and a multiplication symbol. The order of operations tells you to do the "plus" operation inside parentheses first. The numbers involved in a "plus" operation, or sum, are called "terms." The result is their sum.

Then the second operation in the order of operations is to do the multiplication of the sum on the left of the multiplication symbol by the number to the right of the multiplication symbol. The numbers involved in multiplication are called "factors". The result of multiplication is called a "product."

Matching up this vocabulary with what you see, you realize ...

the first factor is the sum of two terms
the end result of evaluating the expression is the product of two factors

What is the rule for a reflection across the y axis?

Ilya [14]

Answer:

When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is transformed into its opposite (its sign is changed). ... the line y = x is the point (y, x). The reflection of the point (x,y) across. the line y = -x is the point (-y, -x).

This rectangular prism is intersected by a plane that contains points B, D, H, and F.

tankabanditka [31]

Answer:

The perimeter of the cross section is 33.3 cm

Step-by-step explanation:

Given: A rectangular prism with height 6 centimeters, length 8 centimeters, and width 7 centimeters. The rectangular prism is intersected by a plane that contains points B, D, H, and F.

We have to determine the perimeter of the cross section.

Since, The plane is drawn diagonally such that it intersect the points B, D, H, and F.(as shown in figure below)

Perimeter of a figure is the sum of its outer boundaries.

We first find the length of diagonal HF.

Since, HGFE , is a rectangle

So, Diagonal of rectangle is given by

$D=\sqrt{Length^2+breadth^2}$

Here, Length = 8 cm

and breadth = 7 cm

So, $D=\sqrt{8^2+7^2}=\sqrt{64+49}\approx 10.63$

Thus, HF = DB = 10.63 cm

Therefore, Perimeter of cross section is DB + BF +FH + DH

= 10.63 + 6 + 6 + 10.63 = 33.26

Thus, the perimeter of the cross section is 33.3 cm
