Answer:

The answer is $1.25

Step-by-step explanation:

She buys 4 notebooks for $2.50 dollars each.

Multiply 2.50 times 4 then you get $10.00

She buys pencils 10 for $0.75 each.

Multiply 10 times 0.75 and you will get $7.50

Then you add $10.00 + $7.50 which will give you $17.50.

Subtract $17.50 from $23.75 which will give you $6.25.

You divide $6.25 by 5 which will give you $1.25.

Expand if necessary combine like terms (7+x)(7-x)=
mina [271]

Answer:

49 - x^2

Step-by-step explanation:

(7+x)(7-x)

We know this is the difference of squares

(a-b) (a+b) = a^2 - b^2

7^2 - x^2 = 49-x^2

We can also FOIL

first = 7*7 = 49

Outer: = 7x

Inner: = -7x

Last : -x*x = -x^2

Add them together

49 +7x-7x - x^2

Combine like terms

49-x^2

How do you do this question?
OLEGan [10]

Step-by-step explanation:

∫ dt / (cos²(t) ⁹√(1 + tan(t)))

If u = 1 + tan(t), then du = sec²(t) dt.

∫ du / ⁹√u

∫ u^(-1/9) du

9/8 u^(8/9) + C

9/8 (1 + tan(t))^(8/9) + C
