I can't tell the exact answer but there should be something given or there should be a similarity/congruency statement
So it's 4x-5 equal to -20 to the second power
-20x-20 =400
The answer is 400
Answer:
f(x)=4x^2
f(2)=4(2)^2
f(2)=4(4)
f(2)=16
2. g(x)=4*2^x
g(2)=4*2^2
g(2)=4*4
g(2)=16
f(2)=g(2)
Both is equal to 16
I hope this help you :)
Step-by-step explanation:
Answer:
Circumference of Circle B=19.625cm
Step-by-step explanation:
The circumference formula is: 2pie(r) = pie(d)
We have diameter of the first circle which is 6. Now, because the diameter of second circle is 25% greater than this,
Hence, we add 25% in 6:
6+25/100 =6+0.25=6.25 cm
Therefore, we have diameter of 6.25 for circle B.
Now, we need to find the circumference of the Circle A.
circumference= pie(d) = pie(6)= 3.14times6= 18.84
Now use the proportional reasoning to find Circumference of Circle B:
circumference of Circle A/diameter Circle A = circumference of Circle B/diameter Circle B
18.84/6=circumference of Circle B/6.25
Cross multiply and divide:
(18.84times6.25)/6 = Circumference of Circle B
Solve:
Circumference of Circle B=19.625cm
Hope this helps!
Mark brainliest if you think i helped! Would really appreciate!
Say width equals x.
Length = 3x - 4
Solve for x: 72 = 2(3x - 4) + 2x
72=6x-8+2x
80=8x
X=10
So width = 10
Length= 3(10) - 4 = 26
