Hint: "4x 2 - 25 = 0" is nearly meaningless. You want 4x^2 - 25 = 0.
Note that both 4x^2 and 25 are perfect squares, so this is the difference of two squares, and is equal to (2x-5)(2x+5)= 0.
Answer:
85in²
Step-by-step explanation:
s = side
triangle: ((b x h) ÷ 2) x 4
((5 x 6) ÷ 2) x 4 = 60in
square: s2(squared not 2)
5² = 25
total sa: 25 + 60 = 85in²
Answer:
EF is the best vector described to intersect both point s
Answer:
30 inches squared
Step-by-step explanation:
First, find the area of the entire frame using length times height. 9*6 is 54 inches squared. Then, find the area of the middle space the same way. 6*4 is 24 inches squared. Lastly, subtract the middle from the entire frame's area. 54-24 is 30 inches squared.
