<span>4x + 1 = 6x - 2, Prove: x = 3/2
-4x =-4x
1 =2x-2
-1 =-1
0 =2x-3
0 =2x+(-3)
2/3=2/3
</span><span>3x - 4 = 2(x + 8), Prove: x = 20
3x- 4 =2x+16
+4 =+4
3x =2x+20
-2x =-2x
1x =20

45 multiply 1/2 and 90 put it in the calculator 90 times 0.5
scientific notation is the standard form of writing numbers in a particular format
scientific notation is writing a number between 0 and 10 times a power of 10
the number to be written is 427 000
so we need to get the decimal point after the first digit from the right
decimal point should come to the right of digit 4
for the decimal to come next to 4 it has to move 5 places to the left. Then its 4.27 multiplied by 10⁵
scientific notation is - 4.27 x 10⁵

Answer:
x³ + x² - 19x - 28
Step-by-step explanation:
(x+4)(x²-3x-7)
x³ - 3x² - 7x + 4x²- 12x - 28
x³ - 3x² + 4x² - 7x - 12x -28
x³ + x² - 19x -28
