Answer:
what is the question.
I am not understand.
please thanks and follow me.
Answer:
Step-by-step explanation:
Area of triangle = 1/2 × Base × Height
Mr.Eastman drew triangle JKL,with a height of 12 inches and a base of 12 inches
Area of JKL = 1/2 × 12 inches × 12 inches
= 72 Square inches
triangle XLZ, with a height of 8 inches and a base of 16 inches. Which triangle has the greater area?
Basically a proportion so it’d be 1in/300 mi = 3in/x mi
cross multiple that out and you get 300•3=x and then just solve for x. the answer should be 900 miles.
Area of square= s^2
12.25=s^2
take the sqrt(12.25) = 3.5
Perimeter of square = 4s
P=4(3.5)
P= 14 m
Answer:
A and B
Step-by-step explanation:
For A, y=2 is the axis of vertical symmetry, meaning a reflection would map the shape onto itself.
For B, x=3 is the axis of horizontal symmetry, meaning a reflection would map the shape onto itself.
For C, a rotation of 90 degrees would make the shape taller vertically and shorter horizontally, therefore it would be wrong.
For D, a translation two units down would move all points down, even though some would need to go up, therefore it would be wrong.
