I need help on #3 please

Answers

Answer 1

Answer: The surface area of a shape is basically the sum of all the areas on a shape.

We’ve been given that the side is 17 mm.

An area of a square is A=s^2, in which s means side. So we do 17^2 to get the area of ONE of the squares.

Once we do that we get that the area of 1 square is 289.

Since there are 6 squares we need to multiply 289 by 6.

Therefore,

SA=1734mm^2

Answer 2

Answer: the surface area is 1734mm
hope this helps:)

Answers

You will need to divide 628 pages by 25 pages.
628/25 = 25.12
Therefore, It will will take 25.12 nights to read the whole book

4. Please help. If PG=−x+10, and GO=−3(x+2), what is the length of PO⎯⎯⎯⎯⎯⎯⎯⎯?

Answers

Answer:36

Step-by-step explanation:

Set PG=GO

-x+10 = -3x-6

Solve for x: x= -8

PG+GO=PO

-x+10-3x-6=PO

combine like terms: -4x+4= PO

Substitute your x value (-8) for x

-(-8)+10-3(-8)-6= 36

PO= 36

Final answer:

The length of line segment PO can be found by adding the lengths of line segments PG and GO. This results in a final equation of PO = -4x + 4.

Explanation:

In mathematical problems involving geometrical shapes, it is common to solve for lengths and distances. To determine the length of PO, we have to sum the lengths of PG and GO because, in a straight line, the total distance from point P to point O is the sum of segment PG and segment GO: PO = PG + GO.

Substitute the given equations into this expression to get: PO = (-x + 10) + (-3(x+2)). Simplifying this we get PO = -x + 10 -3x -6, and by combining like terms, we find that PO = -4x +4.
