The longest side of the triangle has to be less than the sum of the two other sides.

A ⇒ 7 + 8 = 15
B ⇒ 8 + 5 < 14
C ⇒ 6 + 3 < 10
D ⇒ 2 + 6 > 7

The answer is D, because the longest side length (7) is shorter than the two other side lengths (2 and 6).

Answer:

Width 130 ft and

Length 320 ft

Step-by-step explanation:

We are given;

Length of the rectangular base is 70 ft less than three times the width;
Perimeter of the rectangular base is 900 ft

We are required to determine the dimensions of the rectangular base;

Assuming the width of the rectangular base is x ft

Then length will be (3x - 70) ft

But;

Perimeter = 2L + 2W

Thus;

900 ft = 2(3x-70) + 2(x)

900 ft = 6x -140 +2x

1040 = 8x

x = 130

Thus;

Width = 130 ft

Length = 3x -70 = 320 ft

Hence the dimensions of the rectangular base are width 130 ft and length 320 ft

Answer:

$A' = (2,0)$

Step-by-step explanation:

Given

See attachment for ABCD

$k = \frac{1}{2}$ --- the scale factor

Required

The coordinates of A'

From the attachment, we have:

$A = (4,0)$

So:

$A' = k * A$

$A' = \frac{1}{2} * (4,0)$

$A' = (2,0)$
