On the left side of the equation, use the distributive property: 3(3x + 5) = 3(3x) + 3(5) = 9x + 15:
9x + 15 = 4x Get all the x-terms to one side by subtracting 9x from both sides:
9x - 9x + 15 = 4x - 9x
15 = -5x Divide both sides by -5:
15 / -5 = -5x / -5
-3 = x
(3m²)^4 = (3^4) x (m²)^4
3^4 = 81
(m²)^4 = m^8 (To raise an exponent to an exponent, multiply the exponents together.)
Answer: 81m^8
How much juice do you want the box to contain?
If the question is: what number has a square root that, when simplified, is 2.396
then square 2.396: 2.396² ≈ 5.74.
Provided that a ≠ 0, 2a/a = 2, no matter the value of a.
2³ = 8
Setting up a proportion: 2/1,000 = x/1,000,000,000
Multiplying both sides by 1,000,000,000: x = 2,000,000,000 / 1,000 = 2,000,000
If the ratio of boys to girls is 4:5, then the ratio of girls to boys is 1:5, which is 1/5.
1/5 of 1620 = (1/5) x 1620 = 324
se the distributive property (distribute the 3a to both the a and the 2): 3a(a) + 3a(2) = 3a² + 6a
It depend upon the number of significant digits; if two, the answer is 7.0 x 10^10.
Two significant digits give you the 7 and the 0 in the first number.
The exponent is 10 because that is the number of places that you move the decimal point to get it from the right-side end of the number to the place right after the 7.
The answer is D: -3√2/2 = -2.121 7√2/2 = 4.950
I'm sorry that I'm not communicating well with you; are you supposed to use matrices?
