Answer:
the height is 5x-2
Step-by-step explanation:
factor 25x^2+10x-8=(5x-2)(5x+4)
cancel like terms
height = 5x-2
The given triangle is a right triangle.
The tangent of an angle of right triangle is obtained by dividing the opposite side of the angle with the adjacent side of the angle.
The opposite side of angle R is 5 cm and the adjacent side of angle R is 12 cm.
tan R = 5 / 12 = 0.4167
R = arctan (0.4167) = 22.6 degrees.
A=6 because 54/9=6
For b, the picture is not very clear and so I can’t see properly but if it says b/3 then b=45 because 15•3=45
c=11 because 23-12=11
namely, -5, -4, -3, -2, -1, 0, 1. Excluding "2" because n < 2.
Slope intercept formula
Y=-3x-2
Plot a point at the intercept (0,-2)
Then go down 3 over 1 and plot another point (1,-5) then connect with a line
