Answer:
<h2> P = 98 cm</h2>
Step-by-step explanation:
Given one side and diagonal of rectangle we can use Pythagorean theorem to calculate the other side of it.

Perimeter:
P = 2W + 2L = 2•40 + 2•9 = 80 + 18 = 98
Answer:
d = 17.58
Step-by-step explanation:
d = √(x2 - x1)^2 + (y2 - y1)^2 + (z2 - z1)^2
P1(0, 0, 0) P2(8, 7, 14)
Substitute the values in the above equation and you will get
d = √(8 - 0)^2 + (7 - 0)^2 + (14 - 0)^2
= √(64 + 49 + 196)
= √309
= 17.58
The distribution of the -4 was incorrectly put in as -4b when it should be 4b
Complementary angles equal 90 degrees.
The first two graphs angle a and b equal 90’degrees.
The first two are correct
