Answer:
Step-by-step explanation:
we are given a square and rectangle.we want to figure out x which is the width of the rectangle. we are also given a condition i.e
- the area of the square equal to the area of the rectangle
therefore,
recall the formula of the area of square and rectangle so,
now assign variables
thus substitute:
simplify square:
divide both sides by 32:
and we're done!
Answer:
No
Step-by-step explanation:
4,4,5 and 12,7,7 are isosceles triangles because they have two equal sides . 15,15,15 is an equilateral triangle -it has three equal sides
That would be : 3:5 = 12:20....because 3/5 = 12/20
Answer:
D.252
Step-by-step explanation:
In this question, We have to find which rotation about its center will carry a regular decagon onto itself?
A decagon : 10 sided polygon
As we know, a full rotation can be 360°.
For a decagon: 360/10 =36
For a decagon, any multiple of 36 can map onto itself.
In our options only 252 is the multiple of 36.
So, correct answer is option D 252
You add the fractions.
turn it into an improper fraction. you multiply the whole number by the denominator then add the numerator, leaving it over the original denominator.
eg/ 2×4= 8 +3 = 11/4
1×2= 2 +1 = 3/4
find a common denominator.
eg/ 2 and 4 have the common denominator of 4.
then you make the denominators the same.
eg/ 3/2 × 2 = 6/4
add them.
eg/ 11/4 + 6/4 = 17/4
lowest terms.
eg/ 4 1/4
