Answer:
No because the 2 is outside of the parentheses meaning it should be 9^2
Step-by-step explanation:
Answer:
No, I will not simplify 3² first.
Rather I would simplify (12-3) first, i.e., 9.
Then simplify 9² which gives the answer 81.
Step-by-step explanation:
(12-3)²= 9²= 81The surface area "S" of a sphere of radius ris given by the forma

Write the sum, and then write an equivalent expression by collecting like terms and removing parentheses whenever possible.
d. The opposite of - 10t and t - 10t
Answer:
The answer is t.
Step-by-step explanation:
We need to find the sum of opposite of - 10t and t - 10t.
Opposite of -10t = 10 t
So,
10t + (t-10t)
Grouping the numbers,
(10t+(-10t)) + t
= 0 + t
= t
Hence, the answer is t.

He can place his money into an account represented by b(x) = 7x + 75, or into another account represented by c(x) = 75(1.06)x. Which account has the highest value in 2 years? Which account has the highest in 12 years?
Answer:
the answer is the option B
b(x) has the highest value in years; b(x) has the highest value in years
Step-by-step explanation:
x------> the time in years
b(x)----> the value in dollars of a saving account
c(x)----> the value in dollars of another account
we know that

Which of the following would be a possible solution to the system of inequalities given below?
(3,-3)
(1,-7)
(6,4)
(-5,0)
Answer:
(3, -3)
Step-by-step explanation:
A point qualifies as a solution to a system of inequalities if it is true when both of its x and y values are substituted into the both inequalities. Knowing this, let's plug in the first option, (3, -3), into both inequalities.
Let's try 6x + 3y > 3 first. Substitute 3 for x and -3 for y:
[tex]6 (3) + 3 (-3) > 3\\18 - 9 > 3\\9 > 3[/tex]
9 is bigger than 3, so (3, -3) is a solution to that inequality.
Let's try [tex]x -y \geq 4[/tex]. Do the same, substituting the same values:
[tex]3 - (-3) \geq 4\\3 + 3 \geq 4\\6\geq 4[/tex]
6 is bigger than 4, so (3, -3) is a solution to that inequality too.
Since (3, -3) is a solution to both inequalities, it must be the answer.
Find all possible solutions for x and y such that △ABC is congruent to △DEF.
△ABC: sides of length 19, 25, and 3x − 3.
△DEF: sides of length 25, 15, and 5 − y.
△ABC ≅ △DEF when x is ___ and y is ___.
Answer:
Step-by-step explanation:
it means the ABC And DEF have side lengths of 15,19, 25
so 3x-3 = 15
x = 6
5-y = 19
so y = -14

Step-by-step explanation:
[tex] \dfrac{x + 2}{x^3 + 2x^2 - 9x - 18} \div \dfrac{3x + 1}{x^2 - 9} = [/tex]
Factor all polynomials.
[tex] = \dfrac{x + 2}{x^2(x + 2) -9(x + 2)} \div \dfrac{3x + 1}{(x + 3)(x - 3)} [/tex]
[tex] = \dfrac{x + 2}{(x^2 - 9)(x + 2)} \div \dfrac{3x + 1}{(x + 3)(x - 3)} [/tex]
[tex] = \dfrac{x + 2}{(x + 3)(x - 3)(x + 2)} \div \dfrac{3x + 1}{(x + 3)(x - 3)} [/tex]
To divide by a fraction, multiply by its reciprocal.
[tex] = \dfrac{x + 2}{(x + 3)(x - 3)(x + 2)} \times \dfrac{(x + 3)(x - 3)}{3x + 1} [/tex]
Cancel out common factors in the numerator and denominator.
[tex] = \dfrac{1}{3x + 1} [/tex]
