Answer:
C
Step-by-step explanation:
Given the triangles are congruent then corresponding angles are congruent.
The angle corresponding to K in the other Δ is P, they are in the same position Δ APR and Δ WKM
∠ P is congruent to ∠ K
Umm. Where is the question?
Answer:
81/64 or 1 17/64
Step-by-step explanation:
A negative exponent means to flip the fraction
(8/9) ^-2
(9/8)^2
81/64
Changing this to a mixed number
1 17/64
Answer:
The roots are -2 and -3
Step-by-step explanation:
For a quadratic equation given as x² + bx + c, for roots x and y, the sum of roots is equal to the negation of the coefficient of the second term (i.e x + y = - b) while the products of the roots is equal to the coefficient of the second term (i.e x × y = c).
Since for the roots 1 and 6, only the value of c was correct, to get c we use the product of roots. Therefore, c = 1 × 6 = 6
Since for the roots -1 and -6, only the value of b was correct, to get b we use the sum of roots. Therefore:
-b = - 1 + -4 = -5
b = 5
Since the quadratic equation is x² + bx + c, substituting value of b and c and solving:
x² + 5x + 6 = 0
x² + 2x + 3x + 6 = 0
x(x + 2) + 3(x + 2) = 0
(x + 2)(x + 3) = 0
x = -2 or x = -3
The roots are -2 and -3
Answer:
40 and 1/2
Step-by-step explanation:
Multiply 4 1/2 by 1 1/2. Then multiply the product of 4 1/2 and 1 1/2 by 6.
