Answer:
2,025
Step-by-step explanation:
Given:
Third term ar² = 45
Seventh term ar⁶ = 3,645
Find:
ar x ar³
Computation:
From 7th term / 3rd term
ar⁶ / ar² = 3,645 / 45
r⁴ = 81
r = 3
So,
ar² = 45
a(3)² = 45
a = 5
So,
ar x ar³
(5)(3) x (5)(3)³
2,025
Answer:
No
Step-by-step explanation:
2x+8 2(x+4)+4
2(x)+2(4)+4
2x+8+4
2x+12
$30 • 10%
10% = 0.10
30 • 0.10 = 3
The answer is $27. They got $3 off.
$30 - $3 = $27.
Answer:
Blanks top to bottom: 6^2, 36, 9, 108, 101
Step-by-step explanation:
Use PEMDAS which stands for parentheses, exponents, multiplication, division, addition, and subtraction. Listed in this specific order, you must look and solve for each one first, starting with parentheses.
4.
12 × ((4+2)^2/4) - 7
Solve for inside of parentheses first:
12 × ((6)^2/4) - 7
12 × (36/4) - 7
12 × 9 - 7
108 - 7
101
Answer:
![\sqrt[3]{5x+10}=5 / ^{3}\\ 5x+10=125\\5x=115/:5\\x=23](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B5x%2B10%7D%3D5%20%2F%20%5E%7B3%7D%5C%5C%20%205x%2B10%3D125%5C%5C5x%3D115%2F%3A5%5C%5Cx%3D23)
If you mean that :![\sqrt[3]{5x}+10=5](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B5x%7D%2B10%3D5)
this is
![\sqrt[3]{5x}+10=5 /^{3} \\5x+1000=125\\5x=-875/:5\\x=-175](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B5x%7D%2B10%3D5%20%2F%5E%7B3%7D%20%5C%5C5x%2B1000%3D125%5C%5C5x%3D-875%2F%3A5%5C%5Cx%3D-175)
