Hi there!
Let's use x for the width because we know the width is only 1. Next, we'll use 5x for the length because the length is 5 times the width. Now, we can set up an equation to solve for x.
WORK:
x * 5x = 1620
5x^2 = 1620
x^2 = 324
x = 18
ANSWER:
The width of the rectangle is 18 centimeters
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
Answer:
m∠BJK = 146
m∠IJB = 26
Step-by-step explanation:
m∠BJK + m∠IJB = m∠IJK
<em>146 </em>+2x + 2x +<em>26</em> = 172
<em> 172 </em> + 4x = 172
4x = 172 -172 = 0
x = 0
m∠BJK = 146
m∠IJB = 26
Answer:
- 3 and x² + 2x - 3
Step-by-step explanation:
(a)
To evaluate g(1) substitute x = 1 into g(x)
g(1) = 1² - 4 = 1 - 4 = - 3
(b)
Substitute x = x + 1 into g(x)
g(x + 1) = (x + 1)² - 4 ← expand parenthesis using FOI
= x² + 2x + 1 - 4 ← collect like terms
= x² + 2x - 3
N = -1/3 is the answer to the problem
