Answer:
600cm2
Step-by-step explanation:
Area of sheet = Length × Breadth
= (30 × 20) cm2
= 600 cm2
Answer:
3.26 x 102
Step-by-step explanation:
10 squared is 100
3.26 x 100 = 326 because you move the decimal to the right 2 spots
Y= -2x²-3x+2, (form y = ax² +b .x + c
The parabola opens downward & hence it's Vertex is a MAXIMUM.
We know that the axis of symmetry is -b/2a ==>3/(-4) ==>
x= - 3/4 (axis of symmetry. At x=-3/4 , y = 25/8 = 3.125
Hence the axis of symmetry is x= - 3/4 & the vertex is at (-3/4, 25/8)

Answer:
(a + b) = 8x +4
(a - b) = -2x +16
(a * b) = 
Step-by-step explanation:
We have been given the functions;
a(x) = 3x + 10 and b(x) = 5x − 6
Part A:
(a + b) = a(x) + b(x) # we simply add the two given functions
(a + b) = 3x + 10 + 5x − 6
(a + b) = 8x + 4
Part B:
(a - b) = a(x) - b(x) # we simply subtract the two given functions
(a - b) = (3x + 10 ) - (5x − 6)
(a - b) = 3x + 10 -5x +6
(a - b) = -2x + 16
Part C:
(a * b) = a(x)*b(x)
# we simply find the product of the two given functions
(a * b) = (3x + 10)*(5x − 6)
(a * b) =
