5(1+9v) = 5+ 45v
20b+12= 4(5b+3)
And the last one is r=2
Hope this helps!
No because ex:1times5=5 because 1 goes into 5 fiverimes
Answer:
401.92 in²
Step-by-step explanation:
S.A. = 2πr²+2πrh
S.A. = 2π4²+2π4·12
S.A. = 100.48 + 301.44
S.A. = 401.92 in²
Well...it goes towards the funding of social security and medicare...so I am thinking it is the first answer choice
19.8m²
Work:
First you split the shape into a rectangle and a triangle. So now you have a triangle with the sides 4 x 3.6 and a triangle with the sides 4 x 2.7.
Side note: 2.7 comes from subtracting 3.6 off of 6.3.
Rectangle:
A = lw
A = 4 (3.6)
A = 14.4m²
Triangle:
A = 1/2lw
A = 1/2 (4) (2.7)
A = 5.4m²
Then you add the areas of both the rectangle and the triangle together.
14.4 + 5.4 = 19.8m²
