Answer:
x = √30 or -√30
Step-by-step explanation:
480 - 16x^2 = 0
divide both sides by 16
30 - x^2 = 0
-x^2 + 30 = 0
-x^2 = -30
X^2 = 30
x = ± √30
x = √30 or -√30
Answer:
6 ≤ x ≤ 12
Step-by-step explanation:
Instead of solving the area as 1.5*4x, you would do 6*x (multiply 1.5 by 4 and divide 4x by 4).
Then, you can just use division to find the answer.
36/6=6
72/6=12
And since 36≤A≤72, the area can be any number between 36 and 72, so x can be any number between 6 and 12.
Answer:
12.5
Step-by-step explanation:
first you do the one in the 40-15 then you add 50 the you divide by 6
Answer:
d = 8/9
Step-by-step explanation:
All you have to do is add 5/9 to both sides.
d - 5/9 + 5/9 = 3/9 + 5/9
d = 89
So, d = 8/9.
Step-by-step explanation:
✓2 × ✓2 = ✓2×2 = ✓4 = 2
✓5 × ✓7 = ✓5×7 = ✓35
✓2 × ✓18 = ✓2×18 = ✓36 = 6
✓2 × ✓6 = ✓2×6 = ✓12 = ✓4 ×✓3 = 2✓3
