Area of a square
A = s^2, where s = length of side
A = (12 mm)^2
A = 144 mm^2
The area if 144 mm^2.
1) x^2 + 8x + 16 = (x+4)^2
Answer: C. 16
2) x^2 + 4x + 4 = (x+2)^2
Answer: B. 4
Answer:
$412.80
Step-by-step explanation:
480 x 0.20(20%)=96
480-96=384
384 x .075(7.5%)=28.8
384+28.80=412.80
Answer:
The answer should be a positive 3 instead of a negative.
Step-by-step explanation:
The error is in the first step. The equation should've been set up like this...
-14+2y+4=4
-10y+2y=-4
2y=-4+10
2y=6
y=3
Answer:
The standard form of the equation is -3x + y = -19
Step-by-step explanation:
To find the standard form, we first need to note that the slope will be 3 since parallel lines have the same slope. Then we can use point-slope form and manipulate into standard form.
y - y1 = m(x - x1)
y - 5 = 3(x - 8)
y - 5 = 3x - 24
-3x + y - 5 = -24
-3x + y = -19
