Answer:
l = 15 feet
Step-by-step explanation:
l = 2w + 3
First you solve for the width(w)
(2w+15) (w-6) = 0
This means
2w+15=0 OR. w-6=0
First let’s solve 2w+15=0
2w = -15
w = -7.5
Width can’t be negative so that can’t be the answer. So we look at the second equation w-6=0
w= 6
Since we found the width now we can find the length by using the formula l = 2w + 3
= 2(6) + 3
= 12 + 3
= 15 feet
You can check this by using the given area which is 90.
A = lw = 15*6 = 90
Answer:
A
Step-by-step explanation:
They have to be equal if abc and adc are equal
therefore the answer is A
hows that :D
The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable
Step-by-step explanation:
Step 1:
A . 5 with an exponent of 3 times 5 with an exponent of -4
=
=
=
= 1/5
B . (1/4) with an exponent of 3 times (1/4) with an exponent of 2
=
C. Same as above
D. ![\\\frac{(-7)^{5} }{(-7)^{7} } = (-7)^{5-7} = (-7)^{-2} =1/7^{2} = 1/49](https://tex.z-dn.net/?f=%5C%5C%5Cfrac%7B%28-7%29%5E%7B5%7D%20%7D%7B%28-7%29%5E%7B7%7D%20%7D%20%20%3D%20%20%28-7%29%5E%7B5-7%7D%20%20%3D%20%20%28-7%29%5E%7B-2%7D%20%20%3D1%2F7%5E%7B2%7D%20%3D%201%2F49)
Step 2 :
All the above expressions have a value between 1 and 2
The dimensions should be 1 2/3 feet by 1 1/2 feet.
To find these amounts, we simply multiply the length of the snake by the given fraction.
For the length, multiply by 2/3.
For the width, multiply by 1/2.
