Evaluate the expression 1/4 x (3/9 + 5)<br> Choices:1 1/3,1 2/3,5,answer not here.
Luda [366]

Answer:

First option

Step-by-step explanation:

Given the following equation:

\frac{1}{4} \times(\frac{3}{9} +5)

In order to find the answer, we solve the equation in between the parenthesis according to order of operations and then multiply that answer by 1/4.


\frac{1}{4} \times(\frac{3}{9} +5)
5=\frac{5}{1}
\frac{3}{9} +\frac{5}{1}
3\times1=3
9\times1=9
5\times9=45
1\times9=9
\frac{3}{9} +\frac{45}{9}
3+45=48=\frac{48}{9}
\frac{48}{9} \div3=\frac{16}{3}

\frac{1}{4} \times\frac{16}{3}
1\times16=16
4\times3=12
\frac{16}{12} \div2=\frac{8}{6} \div2=\frac{4}{3}
\frac{4}{3} =4\div3=1\frac{1}{3}
=1\frac{1}{3}

Hope this helps.

Solve the following quadratic function by using the quadratic formula: x^2 +<br> 2x - 1 = 2 *
elena55 [62]

Answer:

x = 1 or x = -3

Step-by-step explanation:

ax^{2} + bx + c = 0

x = \frac{-b±\sqrt{b^{2}-4ac } }{2a\\}

as x^{2} + 2x - 1 = 2 ⇔  x^{2} + 2x - 3 = 0, its solution is

x = \frac{-2±\sqrt{2^{2}-4 *1*(-3)} }{2*1}

=  \frac{-2±\sqrt{4+12} }{2} =  \frac{-2±\sqrt{16} }{2} =  \frac{-2±\ 4 }{2}

therefore, x = 1 or x = -3

hope this helps! :D
