Answer:
A) B and C
Step-by-step explanation:
To find the perimeter, add up the lengths of all the sides.
For shape A: 16+16+1+1= 34
For shape B: 8+8+2+2= 20
For shape C: 5+5+5+5= 20
Shapes B and C both have a perimeter of 20. The answer is A, B and C.
I hope this helps!

The other answer is not correct because they are finding the area of the rectangles.
Answer:
centre = (2, - 3 ) and radius = 5
Step-by-step explanation:
the equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k ) are the coordinates of the centre and r is the radius
given
x² + y² - 4x + 6y - 12 = 0 ( add 12 to both sides )
x² + y² - 4x + 6y = 12 ( collect x/ y terms )
x² + 4x + y² + 6y = 12
using the method of completing the square
add ( half the coefficient of the x/ y terms )² to both sides
x² + 2(-2)x + 4 + y² + 2(3)y + 9 = 12 + 4 + 9
(x - 2)² + (y + 3)² = 25 ← in standard form
with (h, k ) = ( 2, - 3 ) and r = = 5
NO,
42 inches wide
<span>height = 84 </span>
Diagonal=square root of ((42*42)+(84*84))=sq root 8820=93.91
<span>She purchased a circular table that is 96 inches in diameter. </span>
as the table is more in than the diagonal,
it will not fit through the door.
<span>Answer: No</span>
Answer:
Question 1: b) Find the total distance from A to B
Distance formula:
d=Square root of (x2-x1)^2+(y2-y1)^2+(z2-z1)^2
d=Square root of (6-4)^2+(12-8)^2+(10-2)^2
d= 9.165 = 9.17 units
27; The first stack is 3 x 3 (= 9). You then multiply 9 by 3 (for each of the 3 stacks). Basically, 3 x 3 x 3.
