Answer:
P = 18.4 units
Step-by-step explanation:
Sides AB and CD are congruent and thus have the same length.
Sides AD and BC are congruent.
The length of side AB is found using the Pythagorean Theorem:
|AB| = √ [ 5² + 1² ] = √26
and
|BC| = √ [ 4² + 1² ] = √17
Then the perimeter is P = 2(√26) + 2(√17), or
10.20 + 8.25, or, to the nearest tenth,
P = 18.4 units
Answer:
b. x = 11/8, x = 59/72.
Step-by-step explanation:
4|8x - 6| = 5|-8x + 7|
square both sides:
16(64x^2 - 96x + 36) = 25( 64x^2 - 112x + 49)
1600x^2 - 1024x^2 - 2800x + 1536x + 1225 - 576 = 0
576x^2 - 1264x + 649 = 0
x = [1264 +/- √(1264^2 - 4 * 576* 649)] / (2*576)
x = 11/8, x = 59/72.
Answer:
-1
Step-by-step explanation:
-40/7+8-23/7
= -40/7+8-23/7
= 16/7-23/7
= -1
Answer: feet: 1, 2, 3, 4, 5
inches: 12, 24, 36, 48, 60
Step-by-step explanation:
There are 12 inches in a foot, therefore if you have 1 foot you have 12 inches, if you have 2 feet you have 24 inches becauase 2*12 = 24 and so on...
Option a. option a has an answer of x=13, while the other problems have solutions of x=5.
