How could Lynn calculate the length of the diagonal of a square?

A. by multiplying the length of the square times itself
B. by adding the lengths of all four sides of the square
C. by multiplying 1/2 by the length of the base times the height
D. by squaring one side length and doubling the value; then taking the square root of that value

D. By doubling one side length and doubling the value; then taking the square root of that value

Step-by-step explanation:

A square as all its sides equal and all the angles in a square are right angles (90°).

Hence, Pythagoras theorem can be applied since the diagonal is the longest side of a square

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
