Answer:
a⁴b⁴ - c⁴
Step-by-step explanation:
The difference of squares formula states that (a - b)(a + b) = a² - b². In this case, a = a²b² and b = c² so a² - b² = (a²b²)² - (c²)² = a⁴b⁴ - c⁴.
<h2>(1)</h2><h2> =(a+b)(3c-d)</h2><h2> =a(3c-d)+b(3c-d)</h2><h2> =3ac-ad+3bc-bd</h2>
<h2>(2)</h2><h2> =(a-b)(c+2d)</h2><h2> =a(c+2d)-b(c+2d)</h2><h2> =ac+2ad-bc-2bd</h2>
<h2>(3)</h2><h2> =(a-b)(c-2d)</h2><h2> =a(c-2d)-b(c-2d)</h2><h2> =ac-2ad-bc+2bd</h2>
<h2>(4)</h2><h2> =(2a+b)(c-3d)</h2><h2> =2a(c-3d)+b(c-3d)</h2><h2> =2ac-6ad+bc-3bd</h2>
Well, let us figure out what the first store will cost.
40*6.95=278
Now for the second store
325*0.8=260
So the first store is $278, while the second store is $260, so Elisa should buy shirts from the second store
Your answer will be letter c
Answer:
Step-by-step explanation:
Are these the only choices?
A would equal 5x^2-32xi+64
B would equal 25x^2-6561
c would equal 25x^2+1024
D would equal 64x^2+25
If there is an option for (5x+8i)(5x-8i) this would be the answer
