Answer:
x = 3 or -7
Step-by-step explanation:
Recall that for a quadratic equation in the form:
Ax² + Bx = C
we need to add (B/2)² to both sides of the equation to
In our case, we are given:
x² + 4x = 21
compared to the general equation above, B = 4, hence we need to add (4/2)² to both sides
x² + 4x = 21 (complete the square)
x² + 4x + (4/2)² = 21 + (4/2)²
x² + 4x + 2² = 21 + 2²
(x+ 2)² = 21 + 4
(x+ 2)² = 25 (take square root of both sides)
(x+2) = ±√25
(x+2) = ±5
hence
(x+2) = +5----> x = 5 - 2 = 3 (answer)
or
(x+2) = -5 ----> x = -5 - 2 = -7(answer)
Answer:
0=0 1=1 2=0 3=0 4=1 5=3 6=1 7=0 8=0 9=1 10=2 11=1 12=2 13=0 14=0 15=3 16=0
Step-by-step explanation:
There was no question so here above is the Dollars spent graph in numbers not dots!
The the scale factor is 9
You can do this by dividing the values of the sculpture by the model
For example:
L: 72/8 = 9
W: 54/6 = 9
H: 81/9 = 9
C is the correct answer 3.785*2.5=9.4625 then multiply by 1000 and you get 9,462.5
Answer:
Step-by-step explanation:
To find the distance between two points in there dimensional coordinate system, we use the formula;
The magnitude for w(6 ,-3 , 6) and x(6, 3, 4)
The correct choice is A.
