Simplify: 10 • 12 + - 15 divided by 5 + 2 (9-4)
Ket [755]
Alright. So the problem is

10*12+-15/5+2(9-4)

Lets break down what we can for now

First focus on parenthesized, multiplying, and dividing in the problem.

10*12=120 15/5=3 (9-4)=5

120+-3+2*5

So the next step, we see 2*5 and a negative -3 on top of a positive symbol.

2*5=10

120-3+10

Now subtract from the left to the right and get your answer.

120-3=117

117+10=127

The roots of $3x^2 - 4x + 15 = 0$ are the same as the roots of $x^2 + bx + c = 0,$ for some constants $b$ and $c.$ Find the orde
Akimi4 [234]

we are given

quadratic equation as

3x^2-4x+15=0

now, we can find b and c from

x^2+bx+c=0

we can see that coefficient of x^2 is 1

so, we will have to make coefficient x^2 as 1

so, we divide both sides by 3

3x^2-4x+15=0

\frac{3x^2-4x+15}{3}= \frac{0}{3}

\frac{3x^2}{3}-\frac{4x}{3}+\frac{15}{3}= \frac{0}{3}

now, we can simplify it

x^2-\frac{4}{3}x+5= 0

now, we can compare it with

x^2+bx+c=0

we get

b=-\frac{4}{3}

c=5

so, we get order pair as

(b,c)=(-\frac{4}{3} , 5)..............Answer
