We can begin by rearranging this into multiplication:
Now we can factor the numerators and denominators:
The factors (x+4) and (x+2) cancel out, leaving us with:
Our answer comes out to be:
Based on the numerator of the second fraction (since we used its inverse), the denominators of both, and the factors we canceled out earlier, the restrictions are x ≠ -4, -3, -2, -1, 4
Answer: The answer is 60 square inches.
Step-by-step explanation: Given that Danny has a triangular pyramid where all the four triangles are congruent. The height and base of one triangle are 6 inches and 5 inches respectively. We are to find the surface area of the pyramid.
The area of one triangle is given by
Since the pyramid consists of four congruent triangles, so the surface area of the pyramid will be
Thus, the answer is 60 sq. inches.
