Step-by-step explanation:

LET THE THREE CONSECUTIVE EVEN INTEGERS BE

(x+2) ,(x+4) ,(x+6)

then

according to the question

4(x+2) – (x+6) = 2(x+4) + 6

4x + 8 – x – 6= 2x + 8+6

3x +2 = 2x + 14

3x – 2x= 14 –2

x= 12

the numbers are

If y=3x^3-2x and (dx)/(dy) = 3, find (dy)/(dt) when x=-2

lesya692 [45]

Answer:

dy/dx = 9x²+2

dy = (9x²+2) dx

dy/dt = (9x²+2) dx/dt

if x = 2 and dx/dt=5 then

dy/dt = (9*2²+2)*5 = 38*5 = 190

One angle of a triangle has a measure of 66. The measure of the third angle is 57 more than half the measure of the second angle

Daniel [21]

So let's say that the second angle is x.

Then we can say that the third angle is $\frac{1}{2}x+57$ .

So then we have three angles:

1) 66°

2) x°

3) ( $\frac{1}{2}x+57$ )°

So then we can add these together and solve for x by setting it equal to the total degrees left in the triangle after subtracting the known angle:

$x+\frac{1}{2}x+57=114$

$\frac{3}{2}x+57=114$

$\frac{3}{2}x=57$

$\frac{2}{3}*\frac{3}{2}x=57*\frac{2}{3}$

$x=\frac{114}{3} =38$

So now we know that the measure of the second angle is 38°. So then we can use this value to solve for the third angle:

$\frac{1}{2}(38) +57=76$

So the values of the angles are:

1) 66°

2) 38°

3) 76°
