Ok I just need someone to explain. Evaluate 12.1p + 11.9r when p=6 & r=7
12.1(_) + 11.9(_) = __+ 83.3 =__
I Put
12.1(6) + 11.9(7) = 71.2 = 83.3 = 155.9
It said that 71.2 was wrong and said the correct one was 72.6
Can someone explain how to do this please and thank you

yes

Step-by-step explanation:

step-by-step explanation:

in the absence of parentheses, i will have to make some assumptions:   i interpret your (3x+5/y^6)(4y^3/5)​ to mean:

3x + 5     4y^(3/5)       (3x + 5)(4)

* =

    y^6             1               y^(6-3/5)

if this is not what you expected, repost your question using parentheses to indicate whether you meant

4y^3

    or   4y^(3/5)

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²
