Answer:
{d,b}={4,3}
Step-by-step explanation:
[1] 11d + 17b = 95
[2] d + b = 7
Graphic Representation of the Equations :
17b + 11d = 95 b + d = 7
Solve by Substitution :
// Solve equation [2] for the variable b
[2] b = -d + 7
// Plug this in for variable b in equation [1]
[1] 11d + 17•(-d +7) = 95
[1] -6d = -24
// Solve equation [1] for the variable d
[1] 6d = 24
[1] d = 4
// By now we know this much :
d = 4
b = -d+7
// Use the d value to solve for b
b = -(4)+7 = 3
Solution :
{d,b} = {4,3}
If you multiply 48cm times 15cm,you get 720cm.Which would leave you with 60 left because 780 minus 720 equals 60.The height of the other base is 60cm.
Step-by-step explanation:
<h3>Factorize : 9x² - y² </h3>
<h3>Applied Formula = a²- b² = (a + b ) (a - b)</h3>
<h3>9x²- 1 y² : </h3>
<h3> = (3x)²– (y)² [ (3x)² = 9x² ]</h3>
<h3> = (3x+y) (3x–y)</h3>
