Answer:

$3x^2 -12x+y$

Step-by-step explanation:

Given expression,

$2x - 6y + 3x^2 + 7y - 14x$

$=(2-14)x + (-6 + 7)y + 3x^2$

$=-12x + y + 3x^2$

$\implies 2x - 6y + 3x2 + 7y - 14x=3x^2 -12x+y$

Since, further simplification is not possible,

Hence, THIRD option is correct.

The formula for the area of a trapezoid with altitude k and bases m and n is . A=k/2 (m+n) solve for m..

SashulF [63]

Answer:

$m=A\times\frac{2}{k}-n$

Step-by-step explanation:

Given : The formula for the area of a trapezoid with altitude k and bases m and n is $A=\frac{k}{2}(m+n)$

We have solve for m .

Consider the given formula $A=\frac{k}{2}(m+n)$

Multiply both side by $\frac{2}{k}$ , we have,

$A\times\frac{2}{k}=m+n$

Now subtract n both side, we have,

$A\times\frac{2}{k}-n=m$

Thus, $m=A\times\frac{2}{k}-n$

I need help i don’t understand this

lys-0071 [83]

Answer:
Angle BAC: 56
ANGLE BCA: 42

Why? First find angle BCA because that angle is on a straight line with another angle on the other side you can do
180-138=42 which is the measurement of angle BCA.

For angle BAC you have to know that the sun of all triangles interior angles is 180 so you do
180-82-42=56
So angle BAC is 56

Hope this helps :D
