Please help! i’ve been looking for all of these answers and it’s not on here and it’s kinda aggravating All the dimensions of a pentagon were multiplied by the same factor, and the area of the figure changed
by a factor of 25. By what factor were the dimensions of the pentagon multiplied?
O 12.5
O 625
O 5
O 50

step-by-step explanation:

it will be a cylinder. with a diameter of 8 and 4 single pieces high

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead

answer:

a=9

step-by-step explanation: lmk if you need a explanation

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
