Answer : E ; 105 square feet
Explanation : 7 x 15 = 105
Answer:
x = 4
Explanation:
For the right hand side:
log base 9 of 8 + log base 9 of (x-2) = log base 9 (8*(x-2))
= log base 9 of (8x-16)
For the left hand side:
2*log base 9 of x = log base 9 of x^2
Now, equating the two sides and solving for x:
log base 9 of (8x-16) = log base 9 of x^2
This means that:
x^2 = 8x - 16
x^2 - 8x + 16 = 0
(x-4)^2 = 0
Therefore:
x = 4
Hope this helps :)
Answer:
(- 3, - 6, 0)
Step-by-step explanation:
Since the dilatation is centred at the origin, multiply each of the coordinates by the scale factor 3
(- 1, - 2, 0) → (- 3, - 6, 0)
<span>2a(cubed) - 2a(squared) - 7a + 7
</span><span>= 2a^3 - 2a^2 - 7a + 7
= 2a^2 (a -1) - 7 (a -1)
= (a - 1)(2a^2 - 7)
(a - 1) and </span>(2a^2 - 7) are factors
answer
<span>A) (a - 1) </span>
−4.5(x−8.9)=12.6
Simplify:
−4.5x+40.05=12.6
Step 2: Subtract 40.05 from both sides.
−4.5x+40.05−40.05=12.6−40.05
−4.5x=−27.45
Step 3: Divide both sides by -4.5.
−4.5x
−4.5
=
−27.45
−4.5
