<span>This is a quadratic equation . We order to equate to zero
</span>2x²<span> – 7 = 9
</span>
2x² - 7-9 = 0
2x² - 16 = 0
This equation is a binomial
2* (x² - 8) = 0
<span>We choose the simplest method . The equation with practice it can be calculated in the memory
</span><span>
The product is equal to 0 if one of the factors is zero
</span>
2≠0 ∨ x² - 8 = 0
x² = √8
x = √8 ∨ x= - √8
Answer : x = √8 ∨ x = -√8
Answer: The histogram is not symmetrical
Corresponding Parts of Congruent Triangles are Congruent
meaning that the same parts of triangles that are congruent will also be congruent
The answer is 800000 because if the number before the number you want to round is 4 or less the number stays the same and all tue other numbers get chnges to 0's
