Answer:
7b, is the answer. they both have a numerator of 7, and the both have x
Step-by-step explanation:
D. some parallelograms are squares
Answer:
Step-by-step explanation:
We can use Tan 27° to find the missing side (in this case, the opposite side to the angle measuring 27°)
Tan A = (opposite side)/(adjacent side)
Tan 27° = y/350
solve for y
350(Tan 27°) = y
178.3 = y (rounded to the nearest tenth)
Its much shorter since you changed 2 inequalities into 1 and you made it be 2 in 1
Answer:
y = ±√3 and ±2i
Step-by-step explanation:
Given the equation y⁴+y²-12 = 0
(y²)²+y²-12 = 0
Let P = y²
Substitute
P²+P-12 = 0
Factorize:
P²+4P-3P -12 = 0
P(P+4)-3(P+4) = 0
(P-3)(P+4) = 0
P-3 = 0 and P+4 = 0
P = 3 and -4
When P = 3
y² = 3
y = ±√3
When P = -4
y² = -4
y² = ±√-4
y = ±2i
Hence the value of y is ±√3 and ±2i
