Simplify the expression 8(3x - 2) - 4(2x + 5)

1 answer:

5 0

If you do the distributed property:
8 times 3x and 8 times -2 & 4 times 2x and 4 times 5 you'll get 24x-16-8x+20. Then you add 16 and 20 together to be left with 24x-8x+36. Subtracting 24x-8x since they have the same variable will give you the final answer of 16x+36.

Given: 2q – r = 4p, 2r = q, r = 2p; Prove: q = r

Gnoma [55]

Answer:

q = r

Step-by-step explanation:

Explanation:-

Given 2q – r = 4p ...(i)

2r = q...(ii)

r = 2p ...(iii)

Substitute 2r = q in equation (i)

2(2r) – r = 4p

3 r = 4 p

2 r + r = 4 p

2 r + 2 p = 4 p

2 r = 2 p

q = r

Answer:

equation

where x equals missing angle

x=52

Step-by-step explanation:

Hello There!

remember the sum of the interior angles of a triangle is 180

so to find the measure of the missing angle we subtract the given angles from 180

180-90-38=52

so the measure of the missing angle is 52

2v2 -5v +3 = 0 how did I do this?

anzhelika [568]

$2v2 -5v +3 = 0 \\ \\\Delta = b^{2}-4ac = (-5)^{2}-4*2*3= 25-24=1\\ \\v_{1}=\frac{-b-\sqrt{\Delta }}{2a} =\frac{5- \sqrt{1 }}{2*2}=\frac{5- 1}{4}= \frac{4}{4}=1\\ \\v_{2}=\frac{-b+\sqrt{\Delta }}{2a} =\frac{5+ \sqrt{1 }}{2*2}=\frac{5+1}{4}= \frac{6}{4}=\frac{3}{2}=1\frac{1}{2}$
