Answer:
x = -4
Step-by-step explanation:
Lets work on this :D
(6x × 2) - 18x = 24
=>12x - 18x = 24
=> -6x = 24
=> x = -4
Please give me brainliest if this helped! :D
Remember the order of operations. The first step in this problem will be to solve the exponent.
Take (2x)^3. Remember that since there are parentheses around 2x, that means you have to cube 2 and x.
(2x)^3 = 2^3 * x^3 = 8x^3
Now multiply that answer by 4 to finish simplifying.
8x^3 * 4 = 32 x^3
Your answer should be: 32x^3
Step-by-step explanation:
Let AB be 5cm
AC be 13cm
According to Pyathagros therom
AC²=AB²+BC²
13²=5²+BC²
169=25+BC²
BC²=169-25
BC²=144
BC=√144
BC=12cm
Area of ∆ABC=½×base×hight
=½×12×5
=½×60
=30cm²
Parimeter of ∆ABC=a+b+c
=5+12+13
=30cm
Since we are given that the student has a brand Y phone, they are one of a sample of only 580 students. Since 80 of those students also own a brand X (they own both) the probability that the random student is one of those is 50/580 = 5/58 = 8.62%
