Olin [163]

Answer: x=-\frac{4}{3}

Step-by-step explanation:

2(x)+2(2)=2(\frac{x}{2})-2(x)

Remove all those parentheses by multiplying. Note: 2 and 2 cancel out.

2x+4=x-2x

Subtract 2x

4=x-2x-2x

Combine like terms;

4=-3x

Divide by -3

\frac{4}{-3}=x

Rewriting it;

x=-\frac{4}{3}

Age at BBM 2019 Question Group 'A Brief answer questions; 1. Integrate the following: S(ax? + 2bx + c)3/2(2xa + 2b) dx 2.
worty [1.4K]

If the integral is

\displaystyle \int (ax^2+2bx+c)^{3/2}(2ax+2b)\,\mathrm dx

substitute u = ax^2+2bx+c and \mathrm du=(2ax+2b)\,\mathrm dx. Then you end up with

\displaystyle \int u^{3/2}\,\mathrm du = \frac25u^{5/2} + C

which in terms of <em>x</em> is

\boxed{\dfrac25(ax^2+2bx+c)^{5/2} + C}

Stella [2.4K]

Answer:

640 students own a bicycle

Step-by-step explanation:

The rate shows that 4 out of 5 students own a bicycle. 4 out of 5 is 80% of the students. Now, we need to find 80% of 800 students.

To do this, we multiply the number of students by .80, which represents 80%.

800 x 0.8 = 640
