Masteriza [31]

I factor it because you can't simplify

2x-8=2(x-4)
X^2+5x+4=(x+1)(x+4)
X^2-16=(x-4)(x+4)
X^2+8x+16=(x+4)(x+4)

If i purchase a product for $79.99 and two accessories for 9.99 and 7.00 how much will i owe after taxes applies 8.75%

ehidna [41]

Answer:

The price will be $105.47

Step-by-step explanation:

Given that i purchase a product for $79.99 and two accessories for $9.99 and $7.00. we have to find how much will i owe after taxes applies 8.75%

Now, the cost price of the product and the two accessories will be

$79.99+$9.99+$7.00

= $96.98

Now, also the tax applies at the rate 8.75%

∴ $Tax=8.75\%\thinspace of\thinspace96.98$

= $8.48575=8.49(approx)$

Hence, the price which i owe after taxes will be $96.98+$8.49=$105.47

If ab = 8 and a^2+b^2=16, then what is the value of (a+b)^2?

aksik [14]

$ab = 8$ & $a^{2} + b^{2} = 16$ so , $( a+b )^{2} = 32$ .

<u>Step-by-step explanation:</u>

Here we have , ab= 8 & a^2+b^2=16 i.e. $ab = 8$ and $a^{2} + b^{2} = 16$ .

We need to find value of (a+b)^2 i.e. $(a+b)^{2}$ :

It's and identity and we know that $( a+b )^{2} = a^{2} +b^{2} +2ab$

⇒ $( a+b )^{2} = a^{2} +b^{2} +2ab$

⇒ $( a+b )^{2} = (a^{2} +b^{2}) +2(ab)$

⇒ $( a+b )^{2} = (16) +2(8)$

⇒ $( a+b )^{2} = (16) +(16)$

⇒ $( a+b )^{2} = 32$

∴ $ab = 8$ & $a^{2} + b^{2} = 16$ so , $( a+b )^{2} = 32$ .
