Answer with explanation:
Two Quadratic expressions are said to be equivalent,if they have same zeroes.But here it has been asked about ,expression which are of the same form,means Instead of being congruent they should be similar.
Expression Equivalent Expression
1. x²+ 3 x + 15 ---------------------- x² + 6 x + 34
2. x² + 8 --------------------- x² + 16
3. x² - 5 x + 5 -------------- x² -12 x + 37
4/3 + 3/4
Make the denominator the same: 12
16/12 + 9/12
= 25/12
Turn that into a mixed number:
= 2 1/25
HOW IS THIS MIDDLE SCHOOL ALGEBRA 1!??? I'm a senior in highschool and i have NEVER seen smthg THIS difficult for a middle schooler...
Let n = number
" product of 3 and a squared number" translates to 3n²
"sum of the number and 4" translates to n + 4
The word "is" becomes your equals sign.
3n² = n + 4 is your equation.
Answer:
180 - 46 - 83 = 51 is the measure of angle C
the exterior angle at angle C, and angle C, are supplementary. since angle C is 51 because of the interior angle triangle sum theorem, then the exterior angle is: 180 -51 = 129 degrees.
Step-by-step explanation:
I hope this helps :)
