Answer:

7m^2 - 11m - 2

Step-by-step explanation:

Subtract (-3m^2 + 10m + 4) from 4m^2 - m + 2:

4m^2 - m + 2

- (-3m^2 + 10m + 4) Now distribute the negative sign:

4m^2 - m + 2

+ 3m^2 - 10m - 4

--------------------------

7m^2 - 11m - 2 is the final answer.

I need to know if it’s A B C OR D

Liula [17]

SOLUTION

Consider the property, opposite angle of a cyclic quadrilateral are supplementary

hence

$\angle NMP+\angle NOP=180^0$

Recall that

$\begin{gathered} \angle NMP=\angle M=(8x-24)^0 \\ \text{and } \\ \angle NOP=\angle O=(4x)^0 \end{gathered}$

Hnece, we have that

$\begin{gathered} \angle M+\angle O=180^0(opposite\text{ angles of a cyclic quadrilateral)} \\ (8x-24)^0+4x^0=180^0 \end{gathered}$

Then

$\begin{gathered} 8x-24+4x=180 \\ 8x+4x-24=180 \\ 12x-24=180 \\ \text{Add 24 t o both sides } \\ 12x-24+24=180+24 \\ 12x=204 \\ \text{divide both sides by 12} \\ \frac{12x}{12}=\frac{204}{12} \\ \text{Then} \\ x=17 \end{gathered}$

Hence

x=17

Since

$\begin{gathered} \angle NOP=(4x)^0 \\ \text{substitute the value of x, we have } \\ \angle NOP=4\times17=68^0 \\ \text{Hence } \\ \angle NOP=68^0 \end{gathered}$

Therefore

The measure of angle NOP is 68⁰

Answer; 68⁰ (The fourth Option )

klio [65]

Answer:

The value of y is 36, and the value of z is 54.

Step-by-step explanation:

y has to be a number that can sit at 2y and then add itself to itself and become 3y.

40 is too high, and 35 is too low. Level it out, and you get 36.
