46) Which of the following is equivalent to the expression below?
ddd [48]

Answer:

Step-by-step explanation:

Your question doesn't match the picture. OCR is often inaccurate!—not that it matters much in this case. None of the choices is correct.

(20-4)·6² + 2 + 18 = 16·6² + 2 + 18

= 16·36 + 2 + 18

= 576 + 2 + 18

= 578 + 18

= 596

The product of x and the sum of 6 and 8 times the square of x
Kamila [148]

Let's separate this problem into several parts:

1. The product of x

AND

2. The sum of 6 and 8

TIMES

3. The square of x

So translating this word problem into numbers, we have:

x TIMES (6+8) TIMES x²

so that is:

x * 14 * x²

which is:

14x^(2+1) = 14x³

Solve for x:<br><br> 2(3x - 9) = 18x<br><br> x = -3/2<br><br> x = 3/2<br><br> x = 0<br><br> x = 6
Mila [183]
Remember yo can do anything to an equation as long as you do it to both sides

so
remember distributive property
a(b+c)=ab+ac

so first distribute
2(3x)+2(-9)=18x
6x-18=18x
minus 6x both sides
-18=12x
divide both sides by 12
-18/12=x
-9/6=x
-3/2=x

easier way is to first divide both sides by 2


x=-3/2
