Answer:
x = -1
Step-by-step explanation:
x = x2 -5x = 3
-5x + 2x = -3x
x = 1
(-1)2 - 5(-1) = 3
-2 + 5 = 3
The width of the pathway is 3m
Step-by-step explanation:
Let the width of the pathway be 'w'
The area will be 130 square meters
The dimensions of the garden is 10 x 7
Area = (10+w) (7+w)
130 = 70 + 17w + w^2
w^2 + 17w - 60 = 0
w^2 +20w - 3w - 60 = 0
w ( w + 20) - 3 ( w + 20) = 0
(w + 20) (w - 3) = 0
w = -20 ( or) w = 3
w is the width and cannot be negative.
So, w = 3 meters
The width of the pathway is 3m
Answer:
52+p
Step-by-step explanation:
The expression says "add p to 52", so we know that we need to sum two values, one of them is the variable 'p', and the other is the value 52.
So, writing this expression in mathematical terms, we have:
52+p
With this expression, we added p to the number 52.
So the correct answer is the last one (the fifth one)
4 out of 10 because the amount of prime numbers from 1- 10 is
2, 3, 5, and 7.
