Answer:
8x(2x+3)-2(x+3)
step by-step explanation:
16x^2+22x+3
16*3=48
2 numbers which have a product of 48 and a sum of 22
=24 and -2
Rewrite the centre term as these two numbers, so
16x^2+24x-2x+3
Factorise each pair of terms.
8x(2x+3)-2(x+3)
From the given inverse function, we have
By definition of inverse function,
so that
Answer:
B. 16.9
Step-by-step explanation:
Reverse Pythagoreans theorem C^2 - B^2 = A^2 so
7^2 - 5^2 = c^2 and it comes out to
49-25 = 24 the square root of that is 4.9 (rounded)
But we are lookign for the perimeter so
4.9 + 7 + 5 = 16.9
