<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

2≠0 ∨ x² - 8 = 0
x² = √8
x = √8 ∨ x= - √8
Answer : x = √8 ∨ x = -√8
The answer for A. Is Yes. For every number of cups, there is one height in centimeters. The answer for B. Is Yes. Each height in centimeters corresponds to one particular number of cups. Hope this helps.
no. he isn't correct because the scale factor is an improper fraction. 2/5 means you have 2 out of 5, but if you have 8 out of 3, that means you have 2 3s and 2 more leftover. it wouldn't be a reduction, it'd be increasing!
Answer:
68+m=185
m=117
Step-by-step explanation:
68 miles before lunch, plus m miles after lunch is a total of 185 miles. Assuming she reaches her destination. That creates the equation 68+m=185
Then, to figure out the miles she travels after lunch we solve for m:
do this by subtracting 68 from both sides. This leaves us with: m=117
