Answer:
3log2+log3+logx
Step-by-step explanation:
log8(3x) can be written as log(8•3x)
Log laws says that log(ab)=log(a)+log(b)
So log (8•3•x)=log8+log3+logx
log8 can be written into prime factorization of log(2^3) and by more log laws that can be written as 3log2
Answer:
Surface area is found:
Surface Area = 1700 cm²
Step-by-step explanation:
(The cereal box is shown in the ATTACHMENT)
The surface area of a rectangular prism can be found by added the areas of all 6 sides of the rectangular prism.
L = length = 20 cm
H = height = 30 cm
W = Width = 5 cm
Side 1:
A(1) = L×H
A(1) = 20×30
A(1) = 600 cm²
Side 2:
As the measurements of the side at the back of side 1 has the same measurement of side 1. then:
A(2) = 600 cm²
Side 3:
A(3) = L×W
A(3) = 20×5
A(3) = 100 cm²
Side 4:
As the measurements of the side at the back of side 4 has the same measurement of side 4. then:
A(4) = 100 cm²
Side 5:
A(5) = H×W
A(5) = 30×5
A(5) = 150 cm²
Side 6:
As the measurements of the side at the back of side 5 has the same measurement of side 5. then:
A(6) = 150 cm²
Surface Area:
Adding areas of all the sides
A(1) + A(2) + A(3) +A(4) + A(5) + A(6) = 600 + 600 + 100 +100 + 150 +150
Surface Area = 1700 cm²
Answer:
(0, 3)
Step-by-step explanation:
midpoint = x1+ x2 ÷2
y1+ y2 ÷ 2
Answer:
The last step is incorrect.
Step-by-step explanation:
5(x² + 9) should be the last step.
The answerer mistakened (x² + 9) for a "difference of squares". You can se the difference of squares factoring when you have a square number being subtracted from another square number. The general rule looks like:
![a^{2} - b^{2} = (a+b)(a-b)](https://tex.z-dn.net/?f=a%5E%7B2%7D%20-%20b%5E%7B2%7D%20%3D%20%28a%2Bb%29%28a-b%29)
"Difference" means the answer when subtracting, but there is a plus sign "+" which means adding.
You can't factor "x² + 9" any further.
