Answer:
x=
17
/9 or x=
25
/9
Step-by-step explanation:
9(3x - 7) ^2= 16
9(3x - 7) ^2-16= 0
as we know that (a-b)^2=a^2-2ab+b^2
9((3x)^2-2(3x)(7)+(7)^2=0
solving this we got the below equation
81x2−378x+425=0
By Factorizing the equation
(9x−17)(9x−25)=0
9x−17=0 or 9x−25=0
x=
17
/9 or x=
25
/9
Hello :
the area is : A= (10×14)/2 =70 <span>square inches. ( answer : a)</span>
Answer:
16π square centimeters.
Step-by-step explanation:
The area of a circle is πr².
Here, we are given the diameter, but we just need to divide it by 2 to get the radius.
8/2 = 4
So, the radius is 4 cm.
Now, we can substitute it into the formula to find the area.
π x 4²
π x 16
16π
So, the area of this circle is 16π.
Answer:
1.25 x 10^2 times greater.
or
125 times greater.
Step-by-step explanation:
The required ratio is 5 x 10^7 / 4 x 10^5
= 5/4 * (10^7 / 10^5)
= 1.25 x 10^2 greater.
