Given: ABCD is a parallelogram and AC ≅ BD
Prove: ∠A = 90°

1. AB≅DC and AD≅BC
2. 2∠A = 180°
3. ∠A + ∠D = 180°
4. ΔBAD≅ΔCDA
5. ∠A = 90°
6. ABCD is a parallelogram and AC≅BD
7. AD≅AD
8. ∠A = ∠D

a. Substitution property of equality
b. Division property of equality
c. Side-Side-Side congruence (SSS)
d. Given
e. Definition of a parallelogram
f. Consecutive angles of a parallelogram are supplementary
g. Corresponding parts of congruent triangles are congruent (CPCTC)
h. Reflexive property of congruence

Plz hurry evaluate the expression a+b where a=8 and b=19

What multiplys to be 1 but adds up to be 4

Evaluate 8x2 + 9x − 1 2x3 + 3x2 − 2x dx. solution since the degree of the numerator is less than the degree of the denominator, we don't need to divide. we factor the denominator as 2x3 + 3x2 − 2x = x(2x2 + 3x − 2) = x(2x − 1)(x + 2). since the denominator has three distinct linear factors, the partial fraction decomposition of the integrand has the form† 8x2 + 9x − 1 x(2x − 1)(x + 2) = correct: your answer is correct. to determine the values of a, b, and c, we multiply both sides of this equation by the product of the denominators, x(2x − 1)(x + 2), obtaining 8x2 + 9x − 1 = a correct: your answer is correct. (x + 2) + bx(x + 2) + cx(2x − 1).
