Let's solve your equation step-by-step.<span><span>
98−<span>x2</span></span>=0</span>
Step 1: Simplify both sides of the equation.<span><span><span>
−<span>x2</span></span>+98</span>=0</span>
Step 2: Subtract 98 from both sides.<span><span><span><span>
−<span>x2</span></span>+98</span>−98</span>=<span>0−98</span></span><span><span>
−<span>x2</span></span>=<span>−98</span></span>
Step 3: Divide both sides by -1.<span><span><span>
−<span>x^2/</span></span><span>1</span></span>=<span><span>−98/</span><span>1</span></span></span><span><span>
x^2</span>=98</span>
Step 4: Take square root.<span>
x=<span>±<span>√98</span></span></span><span><span>
x=<span><span><span>7<span>√2</span></span><span> or </span></span>x</span></span>=<span>−<span>7<span>√2</span></span></span></span>
Answer:<span><span>
x=<span><span><span>7<span>√2</span></span><span> or </span></span>x</span></span>=<span>−<span>7<span>√<span>2

Answer:
25 students had soup for lunch
Step-by-step explanation:
Sandwich : soup
Of all students who purchased lunch this Thursday, 30 chose a sandwich
Let x = number of students who choose soup
Sandwich : soup = 30 : x
If the ratio of students who chose a sandwich to all of those who chose soup was 6:5
Sandwich : soup = 6 : 5
how many of the students had soup for lunch?
Equate both ratios
Sandwich : soup
30 : x = 6 : 5
30 / x = 6 / 5
Cross product
30 * 5 = x * 6
150 = 6x
Divide both sides by 6
x = 150 / 6
= 25
x = number of students who choose soup = 25 students
