Answer:
x^2+5x+6
Step-by-step explanation:
you foil for this so
first: x times x= x^2
outer: x times 2=2x
+
inner: 3 times x=3x
last: 3 times 2=6
so x^2+2x+3x+6
combine like terms
x^2+5x+6
Answer:
arc PQ and arc SR are congruent. arc PS and arc QR are congruent
Step-by-step explanation:
since you didn't give me a graph, im assuming its a circle. The circle is intersected by two chords, with end point PQRS in this order. Use circle properties.
I did it by recognizing that they were all powers of two and that exponents add...so we are looking for a standard magic square for the number 0 thru 8, since 1, 2, ..., 256 are the numbers 2^0 thru 2^8...
The numbers are
128, 4, 8
1, 16, 256
32, 64, 2
Each row, column and diagonal's product is 2^12 or 4096.
Good problem
