14-21= -7
-7 is your answer ^^
Step-by-step explanation:
2x^2+7x-3=0
by doing splitting the middle term we get/ <u>using quadratic eq we get-</u>
Let's solve your equation step-by-step.
2x2+7x−3=0
For this equation: a=2, b=7, c=-3
2x2+7x+−3=0
Step 1: Use quadratic formula with a=2, b=7, c=-3.
x=
−b±√b2−4ac

x=
−(7)±√(7)2−4(2)(−3)

According to the rule of angles and parallel lines, we can say that ∠NKM and ∠KML are equal because they are alternate angles. Since MP is a bisector, ∠KMP = ∠LMP = 1/2∠NKM = 29°. We know that ∠MKL = 90°-∠NKM = 32°. According to the sum of all angles of the triangle, ∠KPM = 180-(32+29) = 119°.
Answer:
x > 77
Step-by-step explanation:
According to order of operations rules, we must carry out division before addition or subtraction. In this case we wish to isolate x and are permitted to simplify the inequality by combining the "like terms" 3 and 8, as follows:
X/7-3>8
+3 +3
--------------
x/7 > 11
The easiest way in which to solve for x is to multiply both sides of this inequality by 7:
7(x/7) > 7(11), or
x > 77
All numbers greater than 77 are part of the solution set.
1 i think? sry if im wrong
