Answer:
[-1, 3, 9]
Step-by-step explanation:
when x = 2: 4-5 = -1
when x = 4: 8-5 = 3
when x = 7: 14-5 = 9
Answer:
(2a - 5) • (3a - 2)
step by step explanation:
Step-1 : Multiply the coefficient of the first term by the constant 6 • 10 = 60
Step-2 : Find two factors of 60 whose sum equals the coefficient of the middle term, which is -19 .
-60 + -1 = -61
-30 + -2 = -32
-20 + -3 = -23
-15 + -4 = -19 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -15 and -4
6a2 - 15a - 4a - 10
Step-4 : Add up the first 2 terms, pulling out like factors :
3a • (2a-5)
Add up the last 2 terms, pulling out common factors :
2 • (2a-5)
Step-5 : Add up the four terms of step 4 :
(3a-2) • (2a-5)
Which is the desired factorization
Final result :
(2a - 5) • (3a - 2)
The second one will be the answer
X= -2 and -7
I answered this on another user but here it is again:
I will give you how to solve 2 of them:
1. The first one is a line, so you know that the total angle of that line is 180 degrees. So: (x-16)+(4x+1)=1805x-15=1805x=195x=39so:(x-16)=39-16=23(4x+1)=4*39+1=157Check: 23+157=180! Correct!
Question 3 is a right angle so it has to add up to 90 degrees(x+15)+50=90x+65=90x=25sox+15=25+15=40Check! 40+50=90...correct again!
The answer to you question is y=10
