Answer:
Area: 12x + 66
Perimeter: 2x + 35
Step-by-step explanation:
Area is the base and the height multiplied, 12(x) + 12(5.5), which is simplified to 12x + 66.
Perimeter is all the sides added together, (x + 5.5) + (x + 5.5) + 12 + 12, which is grouped to be 2x + 11 + 24, then simplified to 2x + 35.
Answer:
Step-by-step: the two triangles are similar, their sides would match up and create the same ratio. However, as you can see
3
5
≠
4
12
≠
5
13
. Each side has a different ratio. Therefore, they don't necessarily have to be similar.
Answer:
I believe the answer is D; 5/20+(-12/20).
Step-by-step explanation:
1/4-3/5
5/20-12/20
-7/20
5/20+(-12/20)
5/20-12/20
-7/20
Hope this helps! :D
The original price is $450.
<u>Step-by-step explanation:</u>
Step 1:
Given details, Discount%, D% = 30 and Selling Price, SP = $315
Step 2:
Write down formula for calculating the Original Price
Selling Price (SP) = Original Price (OP) - Discount (D)
Discount (D) = Original Price (OP) * (D%/100)
Step 3:
Substitute given values in the formula
315 = OP - D
D = 
D = 0.3 OP
Step 4:
Substitute value of D in the first formula
315 = OP - 0.3 OP
315 = OP (1 - 0.3) = 0.7 OP
Original Price, OP = 315/0.7 = $450
