Answer:
The area of rectangle is 
Step-by-step explanation:
we know that
The perimeter of a rectangle is equal to
we have
so
----> equation A
Remember that
The length of a rectangle is twice its width.
so
----> equation B
substitute equation B in equation A
solve for W
Find the value of L
<em>Find the area of rectangle</em>
substitute the values

Answer:
d + c = 122
d - 5 = 2c
so same as saying
2d + 2c = 244
we plug in for 2c
2d + d - 5 = 244
2d + d = 249
3d = 249
d = 249 / 3
d = 83
since d - 5 = 2c
83 - 5 = 2c
78 = 2c
c = 39
there are 39 cats and 83 dogs
39 + 83 = 122
Step-by-step explanation:
Factor the quadratic equation (3x-4)(x+3). Then set the factors equal to zero.
3x-4=0, solve to get 4/3
x+3=0 x=-3
Answer:
35
Step-by-step explanation:
(9 - 3)² - (5 . 4)⁰
= (6)² - (20)⁰
= 36 - 1
= 35
1. 3rd one, because for each x there's only one y.
2. The domain are x's, so it's <span> {2, 4, 6, 8}
3. </span>The range are y's, so it's <span> {1, 2, 3, 4}
