Write the vertex form of the equation and find the necessary coefficient to make it work.
.. y = a*(x +3)^2 -2
.. = ax^2 +6ax +9a -2
You require the y-intercept to be 7. So, for x=0, you have
.. 9a -2 = 7
.. 9a = 9
.. a = 1
The equation you seek is
.. y = x^2 +6x +7
Answer:
3150mm
Step-by-step explanation:
1cm is 10mm you convert it then times it together l x b x h will equal 3150
Answer:
D
Step-by-step explanation:
