Answer:
<h2>A. x ≤2 or x>6</h2>
Step-by-step explanation:
2x+6 ≤ 10 or 2x + 8 > 20
⇔ 2x ≤ 4 or 2x > 12
⇔ x ≤ 2 or x > 6
Answer:
The answer is C
Step-by-step explanation:
Count the height from bottom to up of the box, its 4 units so height is 4, then count from the side, its 10 boxes so its C, 10 and 4.
So to factor
factor out a x+z
(x+z)(x^2-xz+z^2)
the factors are
x+z and x^2-xz+z^2
Answer:
C. x = -12 and x = 2
Step-by-step explanation:
-x²-10x+24=0 Original equation
x²+10x-24=0 Divide everything by -1
(x+12)(x-2)=0 Factor it out
x=-12,2 Solve so that the inside of the parentheses equals 0
<h2>
Answer:</h2>
<u>Area</u> = 2(1/2 × 5 × 5) + 20 × 10
= 2 × 12.5 + 200
= 25 + 200
= 225ft².
