Answer:
81.33 square units
Step-by-step explanation:
Answer:
5cm
Step-by-step explanation:
- In order to find the area of a 2d regular shape such as a square, you need to do length × width = area
- A square has four regular sides, which means they must all be the same length, which in turn means that we only need to find one number, and it must be the square root of 25.
So, the length of each side is 5cm.

Answer:
y^2+xy+x+3y+2
Step-by-step explanation:
first of all we have to multiplies the y in the second bracket for all numbers in the first bracket.
so we have:
xy+y^2+2y
now we have to do the same with 1
x+y+2
now we have to unite the two solutions
xy+y^2+2y+x+y+2
at least we have to added up the similar terms (that have the same literal part)
y^2+xy+x+3y+2
The scale factor is obviously 7, because the 28 divided by 4 equals 7.
This means that the larger octagon's perimeter will be 7 times the smaller octagon's perimeter.
So 34 * 7 = 238.
Answer:
I can't see the numbers well, but the graph is decreasing from (-inf, minimum) and increasing from (minimum, inf). The minimum is the vertex. Hope this helps!
