Solve the equation.
4w2 + 12w +9 = 25

4w(2)+12w+9=25    w=4/5

Step-by-step explanation:

Multiply 2 by 4

Combine like terms to get 20w+9=25

Subtract 9 from both sides and get 20w=16.

Divide both sides by 20. You get .8

Turn this into a fraction then simplify to get 4/5

Hope this helps! Have a nice night (^-^)

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.
