Answer:
correct
Step-by-step explanation:
The perimeter is the sum of the sides.
Rectangle ( opposite sides are congruent ), thus
perimeter = 2x + 2(x + 18) = 2x + 2x + 36 = 4x + 36
Square ( sides are congruent ), thus
perimeter = 4(x + 9) = 4x + 36
The perimeters are the same, so the student is correct
Ok, angle C = 90
D = ? E = 32
Because angle E = 32 the angle inside the bigger triangle is the same size.
( They are the size because they have joint beginnings.)
So, 90 + 32 = 122
And, 180 - 122 = 58
answer:
640,000
step-by-step explanation:
to find the answer, we need to determine whether 41,267 is closer to 40,000 or 50,000.
looking at the numberline, we can conclude that the placement of 641,267 is closer to 640,000, not 650,000.
therefore, the answer is 640,000. (see image attached)

Answer:
slope of the line is (1)
Step-by-step explanation:
Set of points are R( -1, 1 ) S( 2, 4 ) and T( 6, 8 )
We have to find the slope of the line for which these points are collinear.
Since we know slope m = 
for points R and S m = 
=
= 1
Therefore, slope of the line is (1)
