Solve the equation by using the Square Root Property.<br><br><br><br> 16x2 + 16x + 4 = 81
Maslowich

Answer:

x = \dfrac{7}{4}, x = \dfrac{-11}{4}              

Step-by-step explanation:

We are given the following equation in the question:

16x^2 + 16x + 4 = 81

We have to find the solution of the equation using square root property.

We can solve the equation as:

16x^2 + 16x + 4 = 81\\(4x)^2 + 2(4x)(2) + (2)^2 = 81\\\text{Identity: }(a+b)^2 = a^2 + b^2 + 2ab\\\Rightarrow (4x+2)^2 = 81\\ \Rightarrow (4x+2) = \sqrt{81}\\ \Rightarrow (4x+2) = \pm 9\\ \Rightarrow (4x+2) = 9, (4x+2) = -9\\\Rightarrow 4x = 7, 4x = -11\\\Rightarrow x = \dfrac{7}{4}, x = \dfrac{-11}{4}

is the required solution of the equation.

A percent can be found by dividing the part by the whole, or

part/whole

In this case, the part is the amount he spent on fruit. The whole is the total amount he spent.

amount spent on fruit/ total amount spent

He spent $18 on fruit, and $60 in total.

$18/ $60

Divide 18 by 60

18/60

0.3*100=30

0.3--> 3.0 --> 30

30%

He spent 30% on fruit.
