If the product of two positive consecutive odd integers is 63, what’s the larger number ?

myrzilka [38]

For this case we have:

$x$ : Let the variable representing the first odd number

$x + 2$ : Let the variable representing the consecutive odd number at x.

According to the statement we have:

$x (x + 2) = 63\\x ^ 2 + 2x = 63\\x ^ 2 + 2x-63 = 0$

We found the solution by factoring:

We look for two numbers that, when multiplied, result in -63 and when added, result in 2. These numbers are +9 and -7.

$9-7 = 2\\9 * (-7) = -63$

Thus, we have:

$(x + 9) (x-7) = 0$

Therefore the solutions are:

$x_ {1} = - 9\\x_ {2} = 7$

We choose the positive value, so we have:

$x = 7\\x + 2 = 7 + 2 = 9$

Answer:

The largest number is 9

Wut is the answer of -7y+1= -27 step by step

Natali5045456 [20]

Answer:

$y=4$

Step-by-step explanation:

$-7y+1=-27$

Subtract 1 from both sides:

$-7y+1-1=-27-1$

$-7y=-28$

Divide both sides by -7:

$\frac{-7y}{-7}=\frac{-28}{-7}$

$y=4$

14. Michelle simplified an expression for the perimeter of the rectangle below and got X + 35.

Zigmanuir [339]

Answer:

The correct expression for the perimeter is $P=(\frac{5}{3}x+70)\ units$

see the explanation

Step-by-step explanation:

The complete question in the attached figure

Let

L ----> the length of rectangle

W ---> the width of rectangle

we know that

The perimeter of rectangle is equal to

$P=2(L+W)$

In this problem we have

$L=(\frac{5}{6}x+23)\ units$

$W=12\ units$

substitute the values

$P=2(\frac{5}{6}x+23+12)$

$P=2(\frac{5}{6}x+35)$

$P=(\frac{10}{6}x+70)\ units$

Simplify

$P=(\frac{5}{3}x+70)\ units$

so

Michelle didn't multiply the sum of length and width by 2
