Step-by-step explanation:
A.
15/5 = 3, 21/7 = 3 -- scale factor is 1/3 since he must divide by 3 to get the side lengths for the photo card
B.
Area = width*length, and scale factor is 5. Therefore, the new width is (15*5) and the new length is (21*5), so the new area is 15*5*21*5 = 15*21*5² = 15*21*25 = 315*25 = 7875 in²
The length of line segment OM is 34 cm.
<u>Step-by-step explanation</u>:
- The diagonals of a parallelogram bisect each other (cuts equally into two halves).
- The line segment OM is a diagonal with an intersection point Q.
- The line segment OQ is equal in length as the line segment QM.
Step 1 :
⇒ length of OQ = length of QM
⇒ 2x + 3 = 3x -4
⇒ 3x-2x =4+3
⇒ x = 7
Step 2 :
Subsitute x = 7 in OQ and QM
⇒ length of OQ = 2x+3
⇒ 2(7) + 3 = 17 cm
⇒ length of QM = 3x-4
⇒ 3(7) - 4 = 17 cm
∴ Length of OM = length of OQ + length of QM
⇒ OM = 17+17 = 34 cm

Step-by-step explanation:
Answer:
-1/35
Step-by-step explanation:
* means multiply
because of pemdas you should do three multiplication parts first
(1/4×2/5)+(-1/6×3/2)+(3/7×2/5)
1/20 - 3/12 + 6/35
3/60 - 15/60 + 6/35
-12/60 + 6/35
-1/5 + 6/35
-7/35 + 6/35
-1/35
