The first step for solving this expression is to reduce the fraction with 11.

Now reduce the fraction with

.

Reduce the fraction one more time with

.

To take the root of a fraction,, we must take the root of the numerator and denominator separately. This rule will change the expression to the following:

Since we cannot simplify this fraction any further,, the final answer is going to be

7(3a + 12) = 168 ← ( divide both sides by 7 )
3a + 12 = 24 ← ( subtract 12 from both sides )
3a = 12 ← ( divide both sides by 3 )
a = 4
OR
distribute the parenthesis by 7
21a + 84 = 168 ← ( subtract 84 from both sides )
21a = 84 ← ( divide both sides by 21 )
a = 4
<span>Algebraic expression of product of 2 and the second
power of y
=> Algebraic expression is a combination of integers (numbers), variables (a,
b, c, x, y, ….), exponent (2 5 3 …) that is a rational number and algebraic
operations like subtraction (-), addition (+), multiplication (x) and division
(/).
=> Product – result of multiplication
=> second power of y = y<span>2
</span>=> 2 x y<span>2
</span>Thus, the algebraic expression of product of 2 and the second power of y
is equals to 2 x y2

Sandra did not get enough points.
They needed 15, but got 22 and a -8 as well.
So 22-8 = 14
14<15
