We first add both 19.8 by 19.8 and therefore, that would give us 39.6.
42 - 39.6 = 2.4.
2.4 ÷ 2 = 1.2
1.2 would be the length of each sides.
2 times the cube root of 8x+9=5
divide both sides by 2
cube root of 8x+9=2.5
cube everybody (put to 3rd power)
8x+9=2.5^3
8x+9=15.625
minus 9 both sides
8x=6.625
divie both sides by 8
x=0.828125
Answer:
-2 (6x - y) = -12x + 2y
Step-by-step explanation:
By using the distributive property, you start by multiplying -2 and 6x which gets you -12x. You then multiply -2 and -y (in other words -y = -1y) so, -2* -y would get you 2 as a negative multiplied by a negative is a positive. So, adding them together would get your final answer: -2 (6x - y) = -12x + 2y
D. Sasha's method is exponential because it increases by a fixed factor, and Mona's method is linear because it increases by a fixed number.
Hope this helps!~
