Answer:
n = -7,6
Step-by-step explanation:
n(n+1)+3=45
distributive property: a(b+c) = ab+ac
n²+n+3 = 45
n²+n -42 = 0
factor now
(n+7)(n-6) = 0
n = -7,6
Answer: where’s the diagram
Step-by-step explanation:
Y=8
your teacher is introducing algebra
f (x) = a(x - h)^2 + k, where (h, k) is the vertex of the parabola.
Do you see the h and k in your equation?
-h = -(-2) = 2
We see that k = -4.
Our vertex is (2, -4).
Answer:
Step-by-step explanation:
1km=1000 m
1 m=100 cm
1 km=1000×100=100000 cm
27 km=100000×27=2,7 00,000 cms
