Use the left and right triangles. (the two smaller ones -- ACD and BCD)
By similar triangles ACD is similar to BCD
on the left AD/CD is one ratio
On the right CD/DB is the other. These two ratios are equal because they are corresponding parts.
AD / CD = CD / DB
AD = 3
DB = 12
CD = ??
Substitute.
3/CD = CD/12 Cross multiply
36 = CD^2
sqrt(36) = sqrt(CD^2)
CD = 6 <<<<==== Answer.
A <<<<====Answer.
The answer is f(x) = 5 - 2x
Function form means just replace y with f(x).
So given 8x + 4y = 20:
Subtract 8x
4y = 20 - 8x
Divide both sides by 4
y = 5 - 2x
Hi! Could you possibly get a clearer picture? If not I can try my hardest to figure it out
Answer:
512x⁴y¹²
Step-by-step explanation:
its a cube so length x width x height
8xy⁴ times 8xy⁴ times 8xy⁴ is 512x³y¹²
