1) <span>(x – 2)(2x +3) = 2x²+3x-4x -6
the answer is </span><span>2x² – x – 6
2) </span><span>(3x + 2)(4x – 3) =12x²-9x +8x -6
the answer is </span><span>12x2 – x – 6
3) </span><span>(4p – 2)(p – 4) = 4p²-16p-2p+8
the answer is </span><span>4p2 – 18p + 8
4) since </span><span>A = 2r2 + 2rh
so </span>A = 2(3x – 2)² + 2(3x – 2)(<span>x + 3)
= </span>(3x – 2) ( 2(3x – 2) + 2 (x + 3))
A =(3x – 2) ( 10x+2)<span>
</span>
Answer:
slope = - 2/3,y = -2
Step-by-step explanation:
- Make y the subject of the line 3y + 6 = -2x.
- Divide throughout by three to get the slope.
- Get the y - intercept by substituting x = 0.
- The slope gotten is -2/3.
- The y - intercept is y = - 2.
- in plotting the graph, make a point at - 2 on the y - axis which is the y - intercept. Then count three steps from the origin on the x - axis towards the negative direction and mark a point on - three.
When solving (-2)5(-2)-8, you would first, following PEMDAS ofcourse, multiply -2 and 5, getting -10. Then you would multiply -2 and -10, which would be positive 20. Lastly, you would subtract 8 from 20, which equals 12.
I cannot find an answer within the options you gave me, but I am 100% sure that (-2)5(-2)-8 equals 12.
Hope this helped in some way! Please mark brainliest! Thank you v much! :)
12
You cancel out the + in problems like this, so it turns into 17 - 5 = 12 ☺️
