Answer: 63
Step-by-step explanation:
14.5x1.5=21.75
15x2.75=41.25
21.75+41.25=63
ΠD = C
πD = 1π
D = 1π/π
D = 1

Answer:
the answer is -3/4 because if you use step by step explanation y= mx+b slope intercept form means y=mx+b use also implicit differentiation
Step-by-step explanation:
To silpify the expression we proceed as follows:
(x+7)/(x^2+4x-21)
Factorizing the given the denominator:
x^2+4x-21
x^2-3x+7x-21
=x(x-3)+7(x-3)
=(x-3)(x+7)
thus plugging back in our expression we have:
(x+7)/[(x-3)(x+7)]
simplifying this we obtain:
1/(x+3)
Answer: 1/(x+3)
