Angle BAC is 45 degrees. The diagonal bisects angle BAD and since all angles in a square are 90 degrees, half of 90 is 45 degrees.

It's 45° because each angle is 90 so div by 2

A store is having a sale on walnuts and chocolate chips. For 2 pounds of walnuts and 5 pounds of chocolate chips, the total cost

oksian1 [2.3K]

It will be $2.50 for each pound of walnuts, and it will be $1 for each pound of chocolate chips.

I know this hold true because when we multiply $2.50 by 2, we get $5, and add that to the other $5 from the chocolate chips and we will get $10. We can also multiply $2.50 by 8 and add $3 from chocolate chips to get $20 + $3, or $23.

--Multiplying Polynomials--Use the given formulas to express the volume of each object as a polynomial.

V = L*w*h

Where:

V= Volume

L= Length = x+5

w= width = x-2

h= height = 6

Replacing with the values given:

V= (x+5) * (x-2) * 6

V =[ (x*x) + (x*-2) + (5*X) +5*-2) ] * 6

V= [ x^2 - 2x + 5x - 10 ] * 6

V= [ x^2 + 3x - 10] *6

V= (x^2*6) + (3x*6)+ ( - 10 * 6)

V= 6x^2 + 18x - 60

Although not so common now, consider a phone plan that does not have unlimited texting. Your base plan costs you $30 a month and

german

Answer:

The bill will be $26070.

Step-by-step explanation:

Your base plan costs you $30 a month

And each text sent or received is only 12 cents or $0.12.

Let the messages sent be = x

So, cost for messages become = $0.12x$

Let total bill cost be = y

Now, total bill will comprise of monthly plan charges plus message charges.

So, equation forms:

$y=30+0.12x$

Now, given is that In one month 217,000 messages were sent between two brothers in Philadelphia.

So, their approximate bill will be :

$y=30+0.12(217000)$

=> $y=30+26040$

=> y = 26070

Therefore, bill will be $26070.

31 - 8a = 5 ( - 4 - 5a )

timama [110]

Answer:

Step-by-step explanation:

$31 - 8a = 5(-4 - 5a)$

First, on the right-hand side of the equation, let's distribute the $5$ to each term in the parenthesis:

$31 - 8a = -20 - 25a$

Now, let's move all the terms with an $a$ to the left-hand side, and everything else to the right-hand side of the equation:

$-8a + 25a = -20 - 31$

Let's combine like terms:

$17a = -51$

Finally, let's divide each side by $17$ to get $a$ by itself on the left-hand side of the equation:

$a = -3$
