52² − 48² = (2704 + 2304)(2704 − 2304) = 2,003,200
52² − 48² = (52 + 48)(52 − 48) = 100 * 4 = 400
a² - b² = (a +b)*(a-b)
52² − 48² = 2704 − 2304 = 400

I don't know what a radicals is and I can't really show my work cuz I just do it all in my head but I'll solve it for you.
A) (2)(x^2-5x-4) this one can't be simplified anymore unless you use the quadratic formula which I'm too lazy to do
B) (2x-1)(2x-5)
X=1/2 or 5/2
Answer:
x = 1/4
Step-by-step explanation:
−12x=−3 (Given)
x = 0.25 (Divide) (value became positive because negative was divided by negative).
0.25 in fraction = 1/4
Answer:
22.
Step 1: Find area of inner square = 4 ft × 12 ft = 48ft2
Step 2: Find area of outer shape =
25 ft +11 ft = 36 cm2
Step 3: Area of shaded region = area of outer shape – area of inner square
= 36 ft2 – 48 ft2
= 12 ft2
Answer:
D
Step-by-step explanation:
(6, 24) this ordered pair has an x-value of 6 and a y-value of 24
The only equation, if you substitute those values into it, which works is D.
24 = 4(6)
24 = 24
