Answer:
Step-by-step explanation: use Triangle formula Area= 1/2xbxh
1/2x6x6=18
18 sq inches for one triangle then multiply by 24 for the whole quilt
You got this
The answer is 515. Because 5×103 is 515
Answer:

Step-by-step explanation:
arithmetic sequence formula: 
where
is the first term and
is the common difference
Given:
⇒ 
⇒ 
Given:

⇒ 
⇒ 
Rearrange the first equation to make
the subject:
a = 32 - 9d
Now substitute into the second equation and solve for 
(32 - 9d) + 11d = 106
⇒ 32 + 2d = 106
⇒ 2d = 106 - 32 = 74
⇒ d = 74 ÷ 2 = 37
Substitute found value of
into the first equation and solve for
:
a + (9 x 37) = 32
a + 333 = 32
a = 32 - 333 = -301
Therefore, the equation is: 
Answer:
I'll setup the problem, then you can do the calculations
Step-by-step explanation:
Perimeter = 2width(W) + 2length (L)
Area = LW
L = 2.5 + 2W
LW = 62.5
substitute L in equation for area

a = 2; b = 2.5; c = 62.5
