Answer:
D. 25
Step-by-step explanation:
The left end of the baseline has measure (x-16). In this geometry all of the right triangles are similar, so the short-to-long side ratios are proportional:
(x -16)/12 = 12/16
x -16 = 9 . . . . . . . multiply by 12
x = 25 . . . . . . . . . add 16
The unknown length x is 25.
Answer:
simplify: 2.5 =(y+5)
reorder the terms: 2.5y=(5+y)
remove the parenthesis: 2.5y=5+y
solving: 2.5y=5+y
move all terms containing y to the left, all other terms to the right.
add -1y to each side of the equation
2.5y+-1y=5+y+-1y
combine like terms 2.5y+-1y=1.5y
1.5y=5+y+-1y
combine like terms: y+-1y=0
1.5y=5+0
1.5y=5
divide each side by 1.5
y=3.333333333
simplifying
y=3.333333333
Step-by-step explanation:
The answer will be as shown in the pic 15x^(2) +35x
Answer:
Step-by-step explanation:
F(-5) just means that your substituting the number -5 for every x value. So if you have x+1 this would be -5+1 which is -4
