1. Answer is 14.

you first do 8x6 cause of BEDMAS, which is 48. then subtract 12, which gives you 36. then subtract 36 from 50 because 50 is the total amount it should be on both sides.

50 - 36 = 14

2. Answer is 8

5x3 is 15, + 2 is 17. then 20 - 17 gives you 3. you then have 24 divided by a number, and that number is 8 because 24 divided by 8 gives you three

Solve the Linear Quadratic system of equations y=x^(2)+2x-9 y=-2x+3

Debora [2.8K]

Answer:

(x, y) = (-6, 15) and (2, -1)

Step-by-step explanation:

You can start by subtracting the second equation from the first.

(y) -(y) = (x^2 +2x -9) -(-2x +3)

0 = x^2 +4x -12 . . . . . . collect terms

0 = (x +6)(x -2) . . . . . . . factor

Solutions for x are -6 and +2. These values make the factors zero.

The corresponding solutions for y are ...

y = -2(-6) +3 = 15

y = -2(2) +3 = -1

Solutions to the system of equations are ...

(x, y) = (-6, 15) and (2, -1)

serious [3.7K]

Answer:

He will use the D box because it has a volume of

$27 {ft}^{3}$

Step-by-step explanation:

$a)v = whl \\ = 1 \times 5 \times 3 \\ = 15 {ft}^{3}$

$b) \: v = whl \\ = 3 \times 4 \times 2 \\ = 24 {ft}^{3}$

$c) \: v = \: whl\\ = 2 \times 7 \times 1 \\ = 14 {ft}^{3}$

$d) \: v = whl \\ = 3 \times 3 \times 3 \\ = 27 {ft}^{3}$

hope this helps

brainliest appreciated

good luck! have a nice day!!

In a right triangle the length of a hypotenuse is c and the length of one leg is a, and the length of the other leg is b, what i

swat32

Apply the Pythagoras Theorem

${c }^{2} = {a}^{2} + {b}^{2}$
${9 }^{2} = {7}^{2} + {b}^{2}$
$81 = 49+ {b}^{2}$
$81 - 49 = {b}^{2}$
$32= {b}^{2}$
Take square root of both sides

$b = \sqrt{32}$
$b = 4 \sqrt{2}$
