Answer:
x = ±4
Step-by-step explanation:
Step 1: Write out quadratic
2x² - 5 = 27
Step 2: Add 5 to both sides
2x² = 32
Step 3: Divide both sides by 2
x² = 16
Step 4: Take the square root of both sides
x = ±4
∴ x can equal -4 or 4
Answer:
3(x/4) - 1/2 (x/10) or you can just do 0.7x but I don't think that counts as an expression, so just put 3(x/4) - 1/2 (x/10).
Step-by-step explanation:
F you just want to know what is the greatest common factor of 24 and 40<span>, it is </span>8.
<span>gcf (24,40) = </span><span><span><span><span>24×40</span><span>lcm(24,40)</span></span>=<span>960120</span></span><span><span><span>24×40</span><span>lcm(24,40)</span></span>=<span>960120</span></span></span><span>= 8</span>
I hope this helped. Have a great day❤️
