Answer:
we need circumference which is pie times d
9 pie
Step-by-step explanation:
Answer:
A, D, E
Step-by-step explanation:
The perimeter is all of the sides added together
So, since a rectangle has 2 pairs of parallel congruent sides, or 2l and 2w, anything that would result in 2l+2w would be correct.
A, l+w+l+w=2l+2w
B, l*w cant be simplified more
C, 2*l*w would end up with 2l*w due to pemdas
D, 2(l+w)=2l+2w by distribution
E, (2*l)+(2*w)=2l+2w
Plug the numbers in for x to see which make the equation true.
Answer:
Δ MNO ≅ Δ RST
Step-by-step explanation:
In naming the congruent triangles follow the same order, that is
M is the vertex with 79° and R is the vertex with 79°
MN = 21 and RS = 21
These are the first 2 letter names of the triangles, that is MN and RS
O and T are the third, thus
Δ MNO ≅ Δ RST
