Triangles MOP and MNQ are similar. Find x.<br><br> 2<br><br> 3<br><br> 4<br><br> 5
Diano4ka-milaya [45]

Answer:

x = 3

Step-by-step explanation:

MQ : MN = 5:6

MP : MO = 5:6

MQ/MN = 5/6

Hence, MP/MO = 5/6

(5+x)/(6+(18/5)) = 5/6

5+x = (5/6)(48/5)

5+x = 8

x = 3

Which expression has a coefficient of positive 1 for the the term n?
yanalaym [24]

Answer:

3n^2+n-2

Step-by-step explanation:

Coefficient is the number that we multiply an expression that contains a variable. In all the expressions above the variable is n.

Some examples:

Coefficient of n^2 is 1.

Coefficient of n in n^2+2n+1 is 2.

Solution:

In 5n^2+6n-1 the Coefficient of n is 6.

In 2n^2+5n+1 the Coefficient of n is 5.

In 40^2 - n +9 the Coefficient of n is - 1.

In 3n^2 +n - 2 the Coefficient of n is POSITIVE 1.

We tend to not write 1*n because 1*n=n.
