Answer:
120
Step-by-step explanation:
This shape is made out of two figures, a rectangle with sides 20 and 3.5 and a parallelogram with height 2.5 and base 20. 2.5*20+20*3.5=50+70=120 cubic centimetres. Hope this helps!
Answer:
x = -1 or x = -y
Step-by-step explanation:
Solve for x:
(x + 1) (x^2 + 2 x y + y^2) = 0
Split into two equations:
x + 1 = 0 or x^2 + 2 x y + y^2 = 0
Subtract 1 from both sides:
x = -1 or x^2 + 2 x y + y^2 = 0
Write the left hand side as a square:
x = -1 or (x + y)^2 = 0
Take the square root of both sides:
x = -1 or x + y = 0
Subtract y from both sides:
Answer: x = -1 or x = -y
62 is 50% of 124 (62*2=124)
(2x +3)(2x-3)= 0
x= -3/2 x = 3/2
