Step-by-step explanation:
Weight of fish Eric bought
= Weight of fish at first - Weight remaining
= 7/8 lb - 1/2 lb = 3/8 lb.
Number of fish Eric bought
= (3/8 lb) / (1/64 lb)
= (24/64 lb) / (1/64 lb)
= 24.
Hence Eric bought 24 fishes.
X+79=98 (subtract 79 to isolate x)
X=19 so it is false
Equilateral triangle have the same side lengths. Perimeter = sum of all sides
(4x - 3) + (4x - 3) + (4x - 3) = 63
Remove parentheses
4x - 3 + 4x - 3 + 4x - 3 = 63
Combine like terms
12x - 9 = 63
12x = 72, x = 6
Solution: x = 6
Answer:
x = -2+√3i and -2-√3i
Step-by-step explanation:
The formula for the general formula is expressed as;
x = -b±√b²-4ac/2a
Given the expression
x²+4x+7 = 0
a = 1, b = 4 and c = 7
Substitute
x = -4±√4²-4(1)(7)/2(1)
x = -4±√16-28/2
x = -4±√-12/2
x = -4±√4*-3/2
x = -4±2√-3/2
x = -4±2√3i/2
x = -4+2√3i/2 and -4-2√3/2
x = -2+√3i and -2-√3i
Answer:
F(1)= (1)2 + 2
2+2
=4
F(5)= (5)2 + 2
10+2
=12
F(1) + F(5) = 12+4
=16
