Answer:
and 20.5x
and 6.2y
Step-by-step explanation:
-3-x/5+6.2y+20.5x-3/8y
We are given an expression with 5 terms
The terms that has same variables with same exponent are like terms. WE combine only like terms. Constants are also like terms.
In the given expression , the fractions and 20.5x have same 'x' . so they are like terms. we can combine these terms.
the fractions and 6.2y have same 'y' . so they are like terms. we can combine these terms.
The extended form of 5,688 = 5000 + 600 + 80 + 8.
Answer:
No, it is not a solution. 3-4 is -1
The answer is 20 inches because if it is a square and its perimeter is 80 then you divide by 4 which gives you 20 inches.
Answer:
p = 0, p = 12
Step-by-step explanation:
Given a quadratic equation in standard form
ax² + bx + c = 0 then the nature of its roots is given by the discriminant
Δ = b² - 4ac
For equal roots b² - 4ac = 0
Given
x² -(p - 2)x + 2p + 1 = 0 ← in standard form
with a = 1, b = - (p - 2), c = 2p + 1, then
[- (p - 2)]² - (4 × 1 × 2p + 1) = 0
(p - 2)² - 4(2p + 1) = 0
p² - 4p + 4 - 8p - 4 = 0
p² - 12p = 0 ← factor out p from each term
p(p - 12) = 0
Equate each factor to zero and solve for x
p = 0
p - 12 = 0 ⇒ p = 12
