Hello!
To find the area of a square use the formula A=lw (Area is equal to length times width) in other words multiply the side times side of just the square. Then to find the area of a triangle use the formula A= 1/2 hb ( Area is equal to half of the height times base) therefore you multiply the height times the base and then multiply it by 1/2 or 0.5 in decimal form ( or just divide by 2, either way works the same). Then add the area of the square and triangle together. (To find the height of the triangle you need to subtract 10 from 16, in other words 16-10. To find the base of the triangle you need to do 10-6.)
Hope this helps!
Answer:
54 feet
Step-by-step explanation:
The perimeter of the room is the sum of wall lengths:
2·(15 feet) + 2·(12 feet) = 30 feet + 24 feet = 54 feet
The border should be cut to 54 feet.

<em>Comment on the question</em>
This seems to be a math problem designed to get you to figure the perimeter of the room. If you were actually installing wallpaper, you might want to cut the border in four (4) pieces, each slightly longer than the corresponding wall. That way any lack of squareness in the corners could be managed more easily, and the possibility of a gap at the seam could be eliminated.
Answer:
y = 3x + 2 is the equation
Step-by-step explanation:
y intercept is where x is 0 that means y intercept is 2.
slope is change in y over change in x which is 3
1,3,and 4 because for 1 and 3 if you factor it out you can get (x+3)(x-7) which if you solve it it creates them to be -3 and 7. The 4 one is already factored you just solve it and it also becomes -3 and 7. The - outside the parentheses is nothing.
Answer:
4777.28 N
Step-by-step explanation:
The gravitational force down the slope is given by the formula;
(mass *g * sin θ )
where;
θ is the angle of inclination of the slope
g is the gravitational pull
We plug in the given values into the above expression;
(4,000 x 9.8 x sin 7) = 4777.28 N.
The frictional force must equal to 4777.28 N (pointing up the slope).
