Answer: I think the answer would be 10( 5 + 3)

Step-by-step explanation:

first you add 5 and 3 together and you get 8

the multiply 8 times 10

and you get 80

And lastly to check your answer you add 50+30 together and u also get 80

Answer:

Number 2

Step-by-step explanation:

The reason is because you are multiplying 10 by 5 and three this what it would look like

10(5+3)

10( Times) 5= 50

10(times) 3 = 30

50+30

Can someone please help me and explain

julia-pushkina [17]

Answer: (x-2) inches.

The question asks for length in square inches. There is no such thing. It should read in inches. Since it is a square frame, we can take the square root of (x^2-4x+4), which is (x-4). This is in incnes

Step-by-step explanation:

(x-4)*(x-4) = x^2-4x+4

Write a short paragraph composes at least 10 sentences<br>discussing factors affecting solubility

kumpel [21]

Answer:

Step-by-step explanation:

Solubility can be defined as the ability of a solute (could be solid, liquid or gas) to dissolve in a solvent in order to produce a solution. There are several factors affecting solubility which includes (basically four) temperature, polarity, surface area of solute particles and pressure of gases. Generally, an increase in temperature leads to an increase in the solubility of a solute in a solvent. This is because an increase in temperature will increase the average kinetic energy of molecules in the solution which leads to increase interaction between the solute and solvent particles. There is a general saying of "like dissolve like" when discussing polarity. For example, organic solvents are used to dissolve organic solutes (just as petrol is used to wash grease off hands and surfaces). Hence, when the solute and solvent have the same polarity, solubility occurs easily, otherwise solubility may be difficult or may not even occur. A reduced/smaller surface area of the solute leads to an increase in solubility as this makes it easy for the solute particles to interact easily with the solvent. In gases, an increase in pressure increases the interaction between the gaseous molecules of the solute and the solvent, thus leading to an increased solubility. Pressure does not affect solubility in solids and rarely in liquids.

How much material is needed to construct a triangular tent that is 6 feet wide 4 feet tall and 8 feet long with side measurement

jonny [76]

Answer: 152ft^2

The amount of material needed to construct the tent is 152ft^2

Step-by-step explanation:

The amount of material needed to construct a triangular tent= the surface area of the triangular tent.

S.A = area of the 2 side rectangles + area of the 2 side triangles + area of the base.

S.A = Ab + At + Ar ....1

Area of the base Ab= Length × width = 8×6 = 48ft^2

Area of the two triangles At = 2 × 0.5 × width × height

At = width × height = 6×4 = 24ft^2

Area of the two rectangles Ar = 2 × side measurement × length

Side measurement is given as 5ft.

or it can be calculated using;

Side length can be calculated using Pythagoras theorem.

Examining the figure attached, we can see that;

Side breadth b = √(h^2 + (w/2)^2)

b = √(4^2 + (6/2)^2) = √(16+9) = √25

b = 5ft

Ar = 2×5×8 = 80ft^2

From eqn1, S.A can be solved as;

S.A = 48 + 24 + 80

S.A = 152ft^2
