Can anyone solve this​

see explanation

Step-by-step explanation:

Consider the left side

+ ← combine into a single fraction

= ← expand and simplify numerator

= [ sin²A + cos²A = 1 ]

=

= ← factor out 2 on the numerator

= ← cancel (1 + sinA) on numerator/ denominator

=

= 2secA = right side, thus verified

two? xd

step-by-step explanation:

answer: c

substitute in the values.

for a:

f(0) = 0 + 9

f(0) = 9

a is a solution.

for b:

f(7) = 14 + 9

f(7) = 23

b is a solution.

for c:

f (3) = 6 + 9

f(3) = 15

c is not a solution. it's supposed to be 14.

for d:

f(2) = 4 + 9

f(2)= 13

d is a solution.
