Answer:
B(x)=(x_4)^2+5 that is the answer
For what.. could you finish the question ?
Start with the parentheses first
4.6 -4.4+7.8 then calculate from left to right
= 0.2+7.8 = 8
We are given fractions:
.
Let us convert those both fractions in decimals only to get the better deal.
For first fraction 56/25, if we divide 56 by 25, we get
56 ÷ 25 = 2.24 decimal value.
And for second fraction 32.05/15 if we divide 32.05 by 15, we get
32.05 ÷ 15 = 2.14 (approximately).
2.14 is lesser value, therefore 2.14 is better deal than 2.24.
And finally we could say 32.05/15 is better deal than 56/25.
