If f(x) = 8x2 + 4x - 12. Find f(2) f(2)=

posledela

Answer:

f(2) = 28

Step-by-step explanation:

$\rm f(x) = 8 {x}^{2} + 4x - 12$

$\rm Evaluate \: 8 x^2 + 4 x - 12 \: where \: x = 2: \\ \\ \rm \implies f(2) = 8 \times {2}^{2} + 4 \times 2 - 12 \\ \\ \rm \implies f(2) = 8 \times 4 + 8 - 12 \\ \\ \rm \implies f(2) = 32 - 4 \\ \\ \rm \implies f(2) = 28$

a triangle has 180 degrees.
The tics denote the sides being equal, which means the opposite angles are equal, too. To get the remaining subtract it from 180... 180- 2(56) =68 degrees

Fofino [41]

C, 25. You take half of the variable B, so 5 in this case, because B=10. Then you square it. 5^2 is 25.
