Answer:
x^2 + 10x + 25
Step-by-step explanation:
(B/2) ^2
10/2 = 5
5^2 = 25
Perimeter is the sum of the sides.
4x + 6 +3x + 2 = 57
7x + 8 = 57
7x = 49
x = 7
Answer:
c is actually correct lol
Step-by-step explanation:
g(x) = (x-4)(x+2)
set both (x-4) and (x+2) equal to zero
x-4=0
x=4
& bx+2=0
x=-2
c has 4 and -2 as x values
Angle C corresponds to Angle G.
hope this helps :)
The regression equation which correctly models the data in this table is y = 1.49x - 107.5,
<h3>How to determine the regression equation?</h3>
From the table of data values, we have the following parameters:
∑x = 632
∑y = 404
∑x² = 80.142
∑xy = 51.448
Mathematically, the regression equation is represented by the following slope equation:
y = Bx + A
Next, we would determine A by using this expression:
A = (∑y·∑x² - ∑x·∑xy)/(n∑x² - (∑x)²)
A = (404×80,142 - 632×51,448)/(5×∑x² - (632)²)
A = (32,377,368 - 32,515136)/(5×80142 - 399,424)
A = -137,768/1286
A = 107.5
For B, we have:
B = (n∑xy· - ∑x·∑y)/(n∑x² - (∑x)²)
B = (5×51,448 - 632×404)/(5×∑x² - (632)²)
B = 1.49.
y = Bx + A
y = 1.49x - 107.5
