Solutions to the equation (x - 21)2 = 25?

First of all use 2 to multiply the numbers in the bracket which will be 2x-42=25then collect like terms which will be 2x=25+42 which will be 2x=67 then 67/2=33.5 or 33whole number 1/2.

false

step-by-step explanation:

whenever we assume a point on a plane then according to geometry it will definitely have 2 dimensions and if it assumed in space then it will have 3 dimensions.

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
