Let's name the number 'n'. Now write an equation. 7*n +n^2 =12Now you can form a quadratic. n^2 +7n-12=0. Now you can use a myriad of methods to solve it. If you still need help, just message me.
Answer:
-4.65< -4 and 2/5
Step-by-step explanation:
To solve, this we can convert the fraction -4 and 2/5 into a decimal so that the values can be more easily compared. When we do this, we get the result that -4 and 2/5 equals -4.4. Now we can clearly see which value is greater because they are written in the same form:
-4.65<-4.4
-4.65<-4 2/5
Answer:
No. They cannot be the measures of the sides of a triangle.
Step-by-step explanation:
<em>Using Pythagorean Theorem (a² + b² = c²) we can find out if these measures match.</em>
<em>The order for </em><em>a</em><em> and </em><em>b</em><em> doesn't matter, but the measure for </em><em>c</em><em> does. </em><em>c</em><em> is the hypotenuse, the longest side of a triangle. With these measures, </em><em>10</em><em> will be the hypotenuse because it is the longest.</em>
6² + 9² = 10² <em>If this is true, then the measures can be sides of a triangle.</em>
117 = 100 <em>6 squared plus 9 squared equals 117 but 10 squared equals 100. They do not match so the answer is no.</em>
C as there are only 3 terms tip- (count how many symbols). And the highest power it goes to is 2 so it’s 5y squared. Hope this helps :)
