Answer: There are no real solutions
Answer:
228 cm²
Step-by-step explanation:
The base of the pyramid is a regular quadrilateral (a square), so there are 4 congruent lateral faces.
The total surface area is therefore:
A = 36 cm² + 4 (48 cm²)
A = 228 cm²
F(h(x)) means wherever you see x in the f(x) function you're gonna plug in the h(x) function:
f(h(x)) = (2x + 3) - 7
= 2x + 3 - 7
= 2x - 4
Answer:
x=90º
Step-by-step explanation:
x=60+30
x=90
In a circle, the parts of the diagonals multiply to equal each other, so 6·4=2x.
2x = 24, x = 12.
