15m + 2n, first you have to pair the matching variables, 8m and 7m along with the sign in front of them. so 8m(+7m), you would then add those then do the same with the other, +4n(postive) and -2n, so subtract 2 from 4 and get 2. put them together and it’s 15m+2

Solve for g.
Y_Kistochka [10]

Answer:

g =6/5                           g=-5/2

Step-by-step explanation:

(5g − 6)(2g + 5) = 0

Using the zero product property

(5g − 6)  =0          (2g + 5) = 0

5g-6+6 =0+6             2g+5-5=0-5

5g =6                          2g =-5

5g/5 = 6/5                  2g/2 =-5/2

g =6/5                           g=-5/2

PLEASEEEEE HELP ASAP!!!
Ne4ueva [31]

Answer:

Step-by-step explanation:

Triangle ABC is a right angle triangle.

From the given right angle triangle

AB represents the hypotenuse of the right angle triangle.

With m∠A as the reference angle,

AC represents the adjacent side of the right angle triangle.

BC represents the opposite side of the right angle triangle.

To determine AB, we would apply the Cosine trigonometric ratio

Cos θ = opposite side/hypotenuse. Therefore,

Cos 52 = 10/AB

0.616 = 10/AB

AB = 10/0.616

AB = 16.23
