Answer:
perimeter is sum of all four sides; two of which are '4j' and other two are 60 inches each
Step-by-step explanation:
P= 2(4j) + 2(60)
We know perimeter is 400 inches
400 = 8j + 120
8j = 280
j = 35
JKLM to WXYZ
JM = 9 ZW = 13.5
JK = 12 WX = 18
the scale factor is what u multiply the original shape to get the coordinates of the other shape.
13.5 / 9 = 1.5
9 * 1.5 = 13.5
12 * 1.5 = 18
so ur scale factor is 1.5 (because if u multiply 1.5 by the original shape, u get the new shape)
Triangle CAT appears to be rotated about the origin clockwise by 90 degrees. If you have graph paper and you draw out CAT, take one point, rotate the paper 90 degrees, and plot the point again as if it were a new graph. Once you're finished, you'll have this graph of C'A'T'.
6+6x you multiply 3 and 2 but you can’t add the 6x because the first 6 doesn’t have an x so it would stay as 6+6x
Hello from MrBillDoesMath!
Answer:
3
Discussion:
34 + 2x = 40 => subtract 34 from both sides
(34-34) + 2x = 40 - 34 => as (34-34) = 0 and 40-34 = 6
2x = 6 => divide both sides by 2
x = 6/2 = 3
Check the answer:
Does 34 + 2x = 40 if x = 3 ?
Does 34 + 2(3) = 40 ?
Does 34 + 6 = 40 ? YES! so the answer checks.
Thank you,
MrB
