To complete a square for ax²+bx+c, you first make a=1.
in this case, a is already 1
move c to the right side: x²+14x=-47
next, add (1/2 of b)² to both sides, in this case, b=14, half of 14 is 7, so x²+14x+ 7²=-47+7²
the left side is now a perfect square: (x+7)²=2
x+7=√2 or x+7=-√2
x=√2-7, or x=-2-√7
D) the answers growth because when the number 7 (in that position) is raised to a power it will grow at the rate of 7 to the power of (x)
29 tables of relationships is the answer to your equation above … THANK ME LATER
130, is the answer.. so here's me having to come back and to explain,because this questions is SO hard.
They ask to round to the ten.
128
^This is ten, so we look to our right which is eight, is higher than 5. 5 is counted as higher. So 8 is over five and if we round 28, it's 30.
WOW, fascinating.
Thanks Brainly's "monitors" such help. -_-
Answer:
NO
Step-by-step explanation:
Triangle A suggests that the triangle is isosceles.
Isosceles:
Triangle with two congruent angles and sides:
7 , 6 , 7
5 , 4 , 5
9, 12 , 9
Triangle B suggests that the triangle is scalene.
Scalene:
Triangle with no congruent angles or sides:
5 , 6 , 7
10 , 15 , 7
12 , 18 , 21
