The product of two consecutive integers is 72. The equation x(x + 1) = 72 represents the situation, where xrepresents the smaller integer. Which equation can be factored and solved for the smaller integer?
Ox2 + x - 72 = 0
O x2 + x + 72 = 0
O x2 + 2x - 72 = 0
o x2 + 2x + 72 = 0

Answers

Answer:

x^2 + x - 72 = 0

Step-by-step explanation:

x(x + 1) = 72 should be re-written in the standard form of a quadratic:

x^2 + x - 72 = 0.  Same as the first answer choice.

Answer:

x^2+x-72=0

Find the x and y intercepts of 10x = -5y

Answers

Answer:

(0,0)


Step-by-step explanation:

To find the x intercept we set y = 0 and solve for x

10x = -5y

10x = 0

x =0

To find the y intercept we set x = 0 and solve for y

10x = -5y

0 = -5y

0=y

The x and y intercepts are 0

(0,0)


Find x. Problem is in the picture

Answers

Answer:

x = 80

Step-by-step explanation:

22 \degree =  (1)/(2) (x \degree - 36 \degree) \n  \therefore \: 22 \degree * 2 =   (x \degree - 36 \degree) \n \therefore \: 44 \degree =   x \degree - 36 \degree \n \therefore \: 44 \degree   + 36 \degree=   x \degree \n \therefore \:  x \degree = 80 \degree \n  \:  \:  \:  \:  \: \huge \red{ \boxed{ \therefore \:  x  = 80 }}

Parallelogram A B C D is shown. The length of A B is (9 x minus 14) inches and the length of D C is (3 x + 4) inches. In parallelogram ABCD, what is DC? (trust me) 13 in.

Answers

Answer:

DC=13\ in

Step-by-step explanation:

we know that

in a parallelogram, opposite sides are congruent

In this problem

AB and DC are opposite sides

therefore

AB=DC

substitute the given values

9x-14=3x+4

solve for x

9x-3x=4+14\n6x=18\nx=3

Find the length of side DC

DC=3x+4

substitute the value of x

DC=3(3)+4=13\ in

Answer:

i just took the test and 13 in. was the right answer
