Answer:
2(4c+1)(c+8)
Step-by-step explanation:
The first thing you should see in this case is that the triangles are proportional.
We have then that:
((a) / (c)) = ((d) / (a))
Step 1:
Go a multiplying:
((a) / (c)) * (a) = (d)
Step 2:
Pass c multiplying:
(a) * (a) = (d) * (c)
Step 3:
Same basis, exponents are added:
a ^ (1 + 1) = (d) * (c)
Step 4:
a ^ 2 = c * d
Finally
((a) / (c)) = ((d) / (a)) -------> a ^ 2 = c * d
Answer:
Like Terms: and .
Coefficients: and .
Constant:
Step-by-step explanation:
"Like terms" are terms whose variables (and their exponents such as the in ) are the same. In other words, terms that are "like" each other.Example: , , and are like terms because they all have .
Coefficients are a number used to multiply a variable. In the above example, the coefficients would be , , and . In your problem, they're and .
Constants are numbers not attached to variables. See the diagram attached.

Answer:
answer: -3.5
Step-by-step explanation:
4.5-5.9
= -1.4
0.2x3-0.2
0.6-0.2
= 0.4
-1.4 ÷ 0.4
= -3.5
10 1/2
10.5 = 10 5/10
but 5/10 can be simplified to 1/2
the answer is 10 1/2
