Let a, b, c, and d be non-zero real numbers. If the quadratic equation ax(cx + d) = -b(cx+d) is solved for x, which of the follo

LiRa [457]

Answer:

Option d

Step-by-step explanation:

given that a, b, c, and d be non-zero real numbers.

$ax(cx + d) = -b(cx+d) \\acx^2+x(ad+bc)+bd =0$

we can factorise this equation by grouping

$(acx^2+xad)+)xbc+bd) =0\\ax(cx+d) +b(cx+d) =0\\(ax+b)(cx+d) =0$

Equate each factor to 0 to get

$x=\frac{-b}{a} , \frac{-d}{c}$

Ratio of one solution to another would be

$\frac{-b}{a} / \frac{-d}{c} \\=\frac{ad}{bc}$

So ratio would be ad/bc

Out of the four options given, option d is equal to this

So option d is right

The legs of a scalene triangle are represented by (x + 4), (x + 8), and ( 2x − 3). Which polynomial expression BEST represents t

ivanzaharov [21]

The perimeter of the triangle is: 4x+9

Step-by-step explanation:

Perimeter is the measurement of boundary of any closed figure.

Given

s1 = x+4

s2 = x+8

s3 = 2x-3

So, the perimeter will be the sum of all three sides

$P = s_1+s_2+s_3\\= (x+4) + (x+8) + (2x-3)\\= x+4+x+8+2x-3\\= 4x+9$

Hence,

The perimeter of the triangle is: 4x+9

Answer:

37°

Step-by-step explanation:

figure consists of 2 6 side polygon

sum of interior angles: 180 x (6 - 2) x 2 =1440

x = 1440 - (135 + 107 + 126 + 325 + 125 + 95 + 120 + 90 + 280) = 37°

RUDIKE [14]

Answer:

d. 3 to the power of 2 multiplied by 1 whole over 4, the whole squared. = 3 to the power of 4 multiplied by 1 squared over 4 squared. = 81 over 16.

Step-by-step explanation:

This is an exercise in PEMDAS, the order of arithmetic operation:

parentheses > exponents > multiplication and division > addition and subtraction.

[(3² × 5⁰)/4]² = [(9 × 1)/4]² = (9/4)² = 81/16

3⁴ × 1²/4² = 81 × 1/16 = 81/16

a. is wrong. 3¹ × 1²/4² = 3 × 1/16 = 3/16

b. is wrong. [(3² × 0)/4]² = [(9 × 0)/4]² = (0/4)² = 0² = 0

c. is wrong. [(3² × 0)/4]² = 0
