Answer:
x = -10
Step-by-step explanation:
Combine like terms and solve for x
3x + 8 = x - 12
3x= x - 20
2x = -20
x = -10
Answer:
16
Step-by-step explanation:
400-150=250
250/15=~16
Given:
Distance between two buildings =
feet apart.
Distance between highway and one building =
feet.
Distance between highway and second building =
feet.
To find:
The standard form of the polynomial representing the width of the highway between the two building.
Solution:
We know that,
Width of the highway = Distance between two buildings - Distance of both buildings from highway.
Using the above formula, we get the polynomial for width (W) of the highway.


Combining like terms, we get



Therefore, the width point highway is
.
Answer:
Step-by-step explanation:
Find attached:
For algebraic division use KCF method.
K - Keep the first fraction
C- Change division to multiplicatin
F -Flip the second fraction.
3) Indenty used: (a -b)² =a² -2ab + b²
Where a = m and b =2
4) Identity used: (a +b)² = a² + 2ab +b²
Where a = w and b = 1
5) Identity used: a² - b² = (a +b)*(a -b)
Where a = z and b = 2
