A = lw
A = 5.45 × 3.275
A = 17.84875
The area of the frame (without rounding) is 17.84875.
The distributive property is a(b + c) = ab + ac
Answer:
LOL
Step-by-step explanation:
Answer:
The answer is X=21
Step-by-step explanation:
Solve for x by simplifying both sides of the equation, then isolating the variable.
Simplify 1/3 and 1/2
It would look like
then
then mutiply 6 to each side and it will look like 21-x = 0
Last, subtract 21 from each side and it will be
21=x
Answer:
see explanation
Step-by-step explanation:
Given a quadratic equation in standard form
ax² + bx + c = 0 ( a ≠ 0 )
Then for the equation to have 2 real roots , the discriminant must be greater than zero , that is
b² - 4ac > 0
x² + x + c = 0 ← is in standard form
with a = 1, b = 1, c = c , then
b² - 4ac > 0
1² - (4 × 1 × c) > 0
1 - 4c > 0 ( subtract 1 from both sides )
- 4c > - 1
Divide both sides by - 4, reversing the inequality as a result of dividing by a negative quantity.
c <
