Answer:
<h2>∗ = 0.4x³</h2>
Step-by-step
We have :
2×(0,4)×15=12
(0,4)^2=0,16
(15y + ∗)^2 = 225y² + 12x³y + 0.16x⁶
= (15y)² + 2×(15y)×(0.4x³) + (0.4x³)²
then
∗ = 0.4x³
D) 20 pages in 1/4 minute
I know that 1/4 of a minute is 15 seconds and to get to 3 to 15 I multiple by 5 I proceed to do the same to 4 which gives me 20 therefore you get 20 pages in 1/4 of a minute
logc(x^2-1) - (logc^5+logc^x) is the right answer.
Answer:
106.5 square units.
Step-by-step explanation:
See the attached diagram.
The pentagon ABCDE consists of three triangles namely Δ ABC, Δ ACD, and Δ ADE when we join the diagonals AC and AD.
So, Area of Pentagon ABCDE = Area of Δ ABC + Area of Δ ACD + Area of triangle Δ ADE.
⇒ Area of Pentagon ABCDE = (31.8 + 39.2 + 35.5) = 106.5 square units. (Answer)
Do I understand coorectly, you have the following equation
6x+1=4x+19
and you want to know what x is?
first, let's put all the expressions with x on one side and all else on the other side:
6x-4x=19-1
and calculate this 2x=18
and divide by 2:
x=9
and this is the answer!
