Multiply the sum of -13/8 and 5/12 by their difference.

REY [17]

Answer:

1421/576

Step-by-step explanation:

Sum = - 13/8 + 5/12 = - 39/24 + 10/24 = - 29/24

Difference = - 13/8 - 5/12 = - 39/24 - 10/24 = - 49/24

Sum * Difference = (-29/24)*(-49/24) = 1421/576

A positive integer squared plus 3 times it’s consecutive integer is equal to 43

Eduardwww [97]

Answer:

the integer is 5

Step-by-step explanation:

x^2+3(x+1)=43

x^2+3x+3=43

x^2+3x+(9/4)=43-3+(9/4)

(x+(3/2))^2=42 1/4

x+(3/2)=sqrt(42 1/4)

x+(3/2)=6 1/2

x=(6 1/2)-(3/2)

x=5

check:

5^2+3(6)=43

25+18=43

43=43

If y varies directly as x and y = 144 when x = 12, what is the value of y when x = 17?

Burka [1]

$y=kx \\ \\
y=144 \hbox{ when } x=12 \\
\Downarrow \\
144=k \times 12 \\
k=12 \\ \\
y=12x \hbox{ and }
x=17 \\
\Downarrow \\
y=12 \times 17 \\
y=204 \\ \\
\boxed{y=204} \hbox{ when } x=17$
