Step-by-step explanation: if there are 7 days in a week and he is saving for 7 weeks, its 7 x 7= 49
Answer:
Step-by-step explanation:
ax+d=bx+e
ax-bx=e- d
(a-b)x = e - d
1) case : a - b = 0
*) e - d = 0 : 0x = 0 all reals solution
**) e - d ≠ 0 no solution in R
2) case : a - b ≠ 0 single solutio : x = (e-d)/(a-b)
Answer:
oooooooooo Missing number is 72.
If diagonals of a parallelogram are perpendicular to each other, this is a rhombus. A rhombus has all sides equal.
In the current scenario, the shorter rhombus is 20 cm long and has a perimeter of 80 cm
Side of rhombus = 80/4 = 20 cm
A quarter of rhombus is right angled triangle with hypotenuse being side of rhombus.
Half length of long diagonal = sqrt (20^2-10^2) = 17.32 cm
Length of longer rhombus = 17.32*2 = 34.64 cm
