A= 42in²
P = 2l + 2w so
(21 x 2) + (2 x 2)
42 + 4 = 46
46 = 21 by 2
Now let's do 6 and 7
(6 x 2) + (7 x 2)
12 + 14 = 26
46 > 26
so 21 by 2 has greater P (perimeter)
Answer:
x=0
Step-by-step explanation:
if something + 1 is 1, that means that 'something' has to be 0, and to make 2x 0, x has to be 0
Answer:
(a) 300
(b)100
Step-by-step explanation:
(a) each figure is 100 student and there are 3 figures at Woodbridge so it's 3*100=300
(b) DuBois=3*100=300
Polk=4*100=400
400-300=100
Answer:
18
Step-by-step explanation:
Given that the distance between DE is 12 And EF is 6
We can determine that the length is the two put together so 12+6=18
Answer:
y = x - 8
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - x - 1 ← is in slope- intercept form
with slope m = -
Given a line with slope m then the slope of a line perpendicular to it is
= - = - =
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = and (a, b) = (9, - 2), thus
y - (- 2) = (x - 9), that is
y + 2 = (x - 9) ← in point- slope form
Distribute right side and rearrange
y + 2 = x - 6 ( subtract 2 from both sides )
y = x - 8 ← in slope- intercept form
