Answer:

t=7 or t=-7

Step-by-step explanation:

To solve for t, we need to get t alone. To do this, perform the opposite of what is being done to the equation. Keep in mind, everything must be performed to both sides.

t^2=49

t is being squared. The opposite of squared is the square root. Take the square root of both sides.

√t^2=√49

t=√49

t=±7

So, t is equal to 7 or -7

Why might algebra tiles not be a good tool to use to factor x² + 18x +80

anyanavicka [17]

Answer:

Algebra tiles would not be a good tool to use to factor because you would need to drag an x-squared tile, 18 x-tiles, and 80 plus tiles and it would take a lot of time to drag that many tiles on the board and there might not be enough space to hold all of them. and do u have time to drag 80 tiles? lol

Answer:

2820 seats
aₙ = 3n + 9

Step-by-step explanation:

This is an AP with:

The first term a₁ = 12
Common difference d = 3
Number of terms n = 40

Number of the seats:

Sₙ = 1/2*n(a₁ + aₙ) = 1/2n(2a₁ + (n - 1)d)
S₄₀ = 1/2*40(12*2 + 39*3) = 2820 seats

Formula of nth term:

aₙ = a₁ + (n - 1)d
aₙ = 12 + (n - 1)*3 = 12 + 3n - 3 = 3n + 9
aₙ = 3n + 9

Answer:

Check the figure a for the complete solution.

Translation in Portuguese: Verifique a figura a para a solução completa.

Step-by-step explanation:

Complete os espaços com os números da tabela, de forma que a soma dos valores em todos os círculos seja zero.

Como

5 + (-2) + (-3) = 5 - 2 - 3 = 0

10 + (-2) + (-8) = 10 - 2 - 8 = 0

0 + (-8) + (8) = 0 - 8 - 8 = 0

-11 + 3 + (8) = -11 + 3 + 8 = 0

-9 + 3 + (6) = -9 + 3 + 6 = 0

-15 + (9) + (6) = -15 + 9 + 6 = 0

-15 + (5) + (10) = -15 + 5 + 10 = 0

-7 + (10) + (-3) = -7 + 10 - 3 = 0

Check the figure a for the complete solution.
