Step by step solution :
Step 1 :
Equation at the end of step 1 :
((3x2 + 2x) - 1) - (x2 - 3x + 4)
Step 2 :
Trying to factor by splitting the middle term
2.1 Factoring 2x2+5x-5
The first term is, 2x2 its coefficient is 2 .
The middle term is, +5x its coefficient is 5 .
The last term, "the constant", is -5
Step-1 : Multiply the coefficient of the first term by the constant 2 • -5 = -10
Step-2 : Find two factors of -10 whose sum equals the coefficient of the middle term, which is 5 .
-10 + 1 = -9
-5 + 2 = -3
-2 + 5 = 3
-1 + 10 = 9
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
Final result :
2x2 + 5x - 5
brainliest plz tried rlly hard on this
Answer:
D
Step-by-step explanation:
Since x is squared, that's a non-linear equation because it's the only answer that, when graphed, doesn't form a straight line
You put a variable for unknown numbers. 5. 96-x and 6. 17+x
Answer:
0.2 < x < 11.8
Step-by-step explanation:
The triangle inequality theorem states that the sum of any two sides of a triangle must be greater than the third side, for it to form a triangle. So, we can set up 3 equations, x + 5.8 > 6, 5.8 + 6 > x, and x + 6 > 5.8. This solves out to x > 0.2, x < 11.8, and x > -0.2. We can disregard that last one, because a side can't be negative. Therefore, we know the possible range of values for x.
I hope I could be of help! Please give brainliest!
Statement Problem: P, Q and R are three buildings. A car began its journey at P, drove to Q, then to R and returned to P. The bearing of Q from P is 058° and R is due east of Q. PQ = 114 km and QR = 70 km. ( Draw a clearly labelled diagram to represent the above information.
Solution:
