Solution = 2(-3)^2 + 9
= 18 + 9
= 27
i am a mathematics teacher. if anything to ask please pm me
To solve this you have to use cross multiplication.
This gives you 3(x-5)=2(x+2)
3x-15=2x+4
x-15=4
x=19
Answer:
b
Step-by-step explanation:
Lets say that the vertical line in Y and Horizontal line in X
Take any point from either the number 8 diagonal or number 17 diagonal and see the value it has on both X and Y line and sum them , u will find the sum is always the same , this is because all the squares made by closest numbers r the same as any of the squares in this , think this as a graph paper that makes more sense if u r trying to understand ....
1.4 / 7
multiply by 10 in both up and down
(1.4*10) / (7*10)
14 / 70
divide by 7
(14/7) / (70/7)
2 / 10
divide by 2
(2/2) / (10/2)
1 / 5
