X^2 * x^2 - 3x^2 * x-5x^2 - 2x^2x + 2 * 3xx + 2 * 5x -4x^2 + 4 * 3x + 4 * 5
Simplify
X^4 - 5x^3 - 3x^2 + 22x + 20
I would choose a hope this helps
Answer:
the value of x is 17 cm
Step-by-step explanation:
The computation of x is shown below:
Here we applied the pythagoreans theorem
x^2 = a^2 + b^2
x^2 = 15^2 + 8^2
X^2 = 225 + 64
x^2 = 289
x = sqrt(289)
= 17
Hence, the value of x is 17 cm
Add the 28 and 42
then divide by 2
there should be 35 kids in group
2x² - 4x - 30
2(x²) - 2(4x) - 2(15)
2(x² - 4x - 15)
