Answer:
Step-by-step explanation:
3x + 2 = 5x - 6
-2x + 2 = -6
-2x = -8
x = 4
3(4) + 2 = 12 + 2 = 14
5(4) - 6= 20 - 6 = 14 for GH
Answer:
Step-by-step explanation: Given a number N. Given two numbers X and Y, the task is to find the sum of all those numbers from 1 to N that are divisible by X or by ... Sn = (n/2) * {2*a + (n-1)* d} ... + (N / (X * Y) - 1) * (X * Y))/ 2;. return S1 + S2 - S3;. } // Driver code. int main().
hope this is right
Answer:
x= -2/5 and x= 3
Step-by-step explanation:
Given equation is,
5x^2 - 13x - 6 = 0
Or, 5x^2 - 15x + 2x - 6 = 0 ( using middle term method)
Or, 5x( x- 3) + 2 (x-3) = 0
Or, (x-3) (5x+2) = 0
Now, x will have 2 answers because it's degree is 2. Total number of values depends on the power of variable.
So, x= 3 or, 5x = -2
Or, x= -2/5
So, the answer is x= -2/5 and x= 3.
What is the question again
Answer:
1. 30°
2.90°
3. 12 units
Step-by-step explanation:
I can't believe there's nothing confirming that this is a parallelogram/a rhombus?! Assuming is awful, and I wish you could say you can't know for sure lol but for the sake of this answer, let's just call it a rhombus. (There was probably some context elsewhere that you didn't put over here, hopefully.)
1.
The reason I say this is: in a rhombus, the diagonals bisect the angles. This means that the diagonals split the angles they meet into two equal parts. That way, it would make sense. m∠QPR=m∠SPR=30°.
2.
If it is a rhombus, the diagonals are perpendicular to each other, so m∠QTP should be 90°.
3.
Diagnonals in a rhombus (and in any parallelogram) bisect each other, so PT=TR=6, and RP=PT+TR=12 units.
Sorry if this is all dreadfully wrong, and I hope I helped you!
