To dilate means to make larger and when dilating a shape you make all sides go up by the same ratio not amount you don't just add the same number to each side. also I have to assume that the sides go in order for every answer. so to start you set up a ratio using the first side take the 16 from the instructions and put it over the first side in the first answer so 16/24 or 2/3 when reduced then take the second side from the instructions and first answer and set them up the same way 28/40 reduced to 7/10 now if these ratios were equal it would be the answer however because 7/10 doesn't equal 2/3 a is not the answer. do the same for all the answers and you will get c to be the answer
We know that
[surface area of the triangular pyramid]=area of the base+3*[area of lateral triangles]
area of the base=12*8/2-----> 48 cm²
area of one lateral triangle=12*10/2-----> 60 cm²
[surface area of the triangular pyramid]=48+3*[60]-----> 228 cm²
the answer is the option
<span>B) 228 cm2</span>

<h3>Answer: 2 different real number solutions </h3>
Both solutions are irrational.
===============================================
Explanation:
The given function f(x) = 5x^2+2x-12 is in the form f(x) = ax^2+bx+c
We see that
a = 5, b = 2, c = -12
Plug those values into the discriminant formula below
D = b^2 - 4ac
D = (2)^2 - 4(5)(-12)
D = 4 - 4(5)(-12)
D = 4 + 240
D = 244
Because D > 0, this means we have two different real solutions for f(x) = 0
The value of D is not a perfect square, so those two solutions or roots are irrational.
