Simplify (7 + 1)2 - (11 +32) 4. O A. 59
O B. 17
O C. -3
O D. -13

the 32 is an exponent. so it’s 3 to the second power.
help !

59

Step-by-step explanation:

I think your equation is supposed to look like this:

(7 + 1)² - (11 + 3²)/4

Follow PEMDAS to solve (Parentheses, Exponent, Multiplication, Division, Addition, Subtraction)

(7 + 1)² - (11 + 9)/4

(8)² - (20)/4

64 - (20)/4

64 - 5

59

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
