Answer: (-0.4, 6.8)
The graph is attached
Step-by-step explanation:
We can find the axis of symmetry using the formula x = -b/2a
x = - -4/2(-5)
x = 4/-10
x = 0.04
Substitute for x and calculate y
y = 
y = 6.8
Answer: <1= 38 and x= 6
Step-by-step explanation: the sum of the angles of a triangle are equal to 180 degrees. Subtract 92 and 50 from 180 to get your answer.
LWH=V
increasse by 10% means times 1.10
increase by 20% is times 1.20
L turns to 1.1L
W turns to 1.1W
H turns to 1.2H
(1.1L)(1.1W)(1.2H)=1.452LWH
so it is increased by 45.2%

If I understood correctly
