Answer:

\boxed{\sf (a + 3)(a + 1)}

Step-by-step explanation:

\sf Factor  \: the  \: following:  \\  \sf \implies  {a}^{2}  + 4a + 3 \\  \\  \sf The \:  factors  \: of \:  3 \:  that \:  sum \:  to \:  4  \\ \sf are \:  3  \: and  \:  1. \\ \\  \sf So,  \\   \sf \implies {a}^{2}  + (3 + 1)a + 3 \\  \\  \sf \implies   {a}^{2}  + 3a + a + 3 \\  \\  \sf \implies a(a + 3) + 1(a + 3)  \\  \\ \sf \implies (a + 3)(a + 1)

Answer:

±6

Step-by-step explanation:

Given the mathematical expression;

√36 < √42 < √49

But, √36 = 6 * 6 = 6²

√49 = 7 * 7 = 7²

Simplifying further, we would substitute the new values respectively;

±[6] < √42 < ±[7]

Therefore, evaluating √36 is equal to ±6.

Sophie [7]

Answer:

The total cost y in dollars of going to the baseball game for x people of a family can be given as:

y=21x+5

Step-by-step explanation:

Given:

At a baseball game:

Cost of car parking = $5

Cost per ticket = $21

To write an equation in the form of y=mx+b representing the total cost of going to the baseball game.

Solution:

The total number of people in the family is = x

Using unitary method to find the cost of tickets for x persons.

If 1 ticket costs = $21

<em>Then, x tickets will cost in dollars</em><em> = </em>21x

Fixed rate for car parking = $5

Thus, the total cost y in dollars of going to the baseball game for x people of a family can be given as:

y=21x+5
