Answer:
72 in²
Step-by-step explanation:
We obtain the value of EC:
From Pythagoras :
EC = √CD² - DE²
EC = √10² - 6²
EC = √100 - 36
EC = √64
EC = 8
To obtain AE:
AE = √AB² - BE²
AE = √(√52)² - 6²
AE = √52 - 36
AE = √16
AE = 4
Hence, we can obtain the areas of each triangle :
△ABE = △ADE
△BCE = △CDE
AREA OF △ABE = 1/2 * base * height
= 1/2 * 4 * 6 = 12 in²
AREA OF △BCE = 1/2 * base * height
= 1/2 * 6 * 8 = 24 in²
HENCE, total area of fabric :
(2 * 12) + (2 * 24)
24 in² + 48 in²
= 72 in²
If we round 6.254 to 6, then 2 * 6 = 12
If we round 54 to 50, then 9 * 50 = 450
Let's check with the appropriate calculations to find out how close we are:
2* 6,254 = 12,508
9 * 54 = 486
So it's close enough :)
Answer:
16
Step-by-step explanation:
The constant is the term without any variables (like letters x or y) attached to it.
Looking at the equation, we see that -14x, 6x, and 2y are all terms with a variable. Only 16 is solely a number.
Thus, the answer is 16.
Answer:
(42.26/100)*120 = $50.712
Step-by-step explanation:
Let's solve your equation step-by-step.
4(a+4)−2=34
Step 1: Simplify both sides of the equation.
4(a+4)−2=34
(4)(a)+(4)(4)+−2=34 (Distribute)
4a+16+−2=34
(4a)+(16+−2)=34 (Combine Like Terms)
4a+14=34
4a+14=34
Step 2: Subtract 14 from both sides.
4a+14−14=34−14
4a=20
Step 3: Divide both sides by 4.
