A rectangle and a triangle with the same base and height have the same area. a. True
b. False

Answers

the answer is false because if you attach to triangles together in a way so that the figure would have 4 straight lines, you will get a rectangle. that means half of a rectangle is a triangle, so the area of both cannot be the same even if they have the same base and height.

for example the base and height of both is 3cm and 5cm.

area of the rectangle then would be,
area= base× height
=3cm×5cm=15cmsquared

then the area of the triangle would be,
area= base×height divided by 2
=3cm×5cm÷2= 7.5cm

so your answer is false
hope this helps....

Write an explicit formula for the sequence 10,9.5,9,8.5,8 then find a8

Answers

an=a1+d(n-1)
a1=first term
d=common differnce
n=which term

minusing 0.5 each time
first term is 10

an=10-0.5(n-1)
8th term
a8=10-0.5(8-1)
a8=10-0.5(7)
a8=10-3.5
a8=6.5

the 8th term or a8 is 6.5
