Roses bought=x
daisies bought=x-4
number of roses and daisies bought=x+x-4=2x-4
Answer:
4x-5
Step-by-step explanation:
The area of a square is
A = s^2
16x^2 - 40x+25 = s^2
Take the square root of each side
sqrt(16x^2 - 40x+25) =sqrt( s^2)
Recognizing that the left hand side is a perfect square trinomial
sqrt((4x-5)^2) = s
4x-5 =s
The side length is 4x-5
Some rhombuses have four right angles
Step-by-step explanation:
1) 13/8−1 1/8
or,13-11/8(taking LCM)
or,2/8
or,1/4
2)let the equation=X
13/8−1 1/8=X
or, 2/8=X
or,1/4=X
X=1/4
Answer:
16/24
Step-by-step explanation:
So you need to get a common denominator before you try to answer the whole question. Turn the denominator into 24. Since you would multiply 8 by 3, multiply the 7 by 3. That would make 21/24. Make the 3 a 24, multiplying it by 8 and doing the same to the 2 making 16/24.
