always plug in x. in this case, x equals 4.
i'm going to first solve 4(2+3x)
1) 4(2+3(4)) use pemdas to solve.
i'm going to multiply whats in the parenthesis first, so 3 times 4=12.
2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)
4 times 2= 8. 4 times 12= 48
4) (8+48)= 56 (answer)
i'm then going to solve 8+12x and plug in 4 for x.
1) 8 +12(4)
multiplying comes before adding, so i'm gonna multiply 12 and 4.
12 times 4= 48.
both equal the same!
the length of o'p' is .
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 .
