Answer:
- 5(x - 4)(x + 4)
Step-by-step explanation:
Given
- 5x² + 80 ← factor out - 5 from each term
= - 5(x² - 16) ← x² - 16 is a difference of squares and factors in general as
a² - b² = (a - b)(a + b), thus
x² - 16 = x² - 4² = (x - 4)(x + 4)
Thus
- 5x² + 80 = - 5(x - 4)(x + 4) ← in factored form
Answer:
13k
Step-by-step explanation:
Given: 
Finding the equivalent expression.
We know the rule of addition is that adding two positive integers will give positive result or sum.
Now, lets find the equivalent expression of
.
∴ 
Hence, the required equivalent expression is 13k.
Answer:
The area of the rhombus is 24 units²
Step-by-step explanation:
The area of a rhombus is half the product of the diagonals.
We can easily calculate the length of the diagonals because they are vertical and horizontal line segments.
We use the absolute value approach.
The length of diagonal BD is |7--5|=|7+5|=|12|=12
The length of diagonal AC=|0--4|=|4|=4
Therefore the area of the rhombus is

Answer:
6^7^3
6^(7×3)
6^21
power of power is multiplied.
divide both denomonator and numerator by 2 so you get 5/12
