Answer:
the formula for the area of a triangle is: Area= 1/2 (length×width)
Surface area of cylinder = 2πrh + 2πr^2
SA for cylinder A = 2π x 2 x 2 + 2π x (2)^2 = 8π + 8π = 16π
SA for cylinder B = 2π x 2 x 4 + 2π x (2)^2 = 16π + 8π = 24π
Answer:
-7 or 4
Step-by-step explanation:
use foil to get the quadratic equation:
x^2+5x-2x-10=18
x^2+3x-10=18
bring "18" to the left:
x^2+3x-10-18
x^2+3x-28
so what*what= -28
and
what+what=3
factors of -28: -7,4 -4,7 14,-2 -14,2 -28,1 -1,28
factors whose sum is 3: 7,-4
so substitute "7,-4" in place of 3:
x^2+7x-4x-28
2) split it in two groups
group 1) x^2+7x
group 2) -4x-28
x^2+7x has a GCF of "x"
x(x+7)
group 2) -4x-28 has a gcf of "-4"
-4(x+7)
3) (x-4) (x+7)=0
x-4=0
x=4
x+7=0
x=-7
x=4,-7

Answer:
190 Baseballs
Step-by-step explanation:
Since he put 304 baseballs into 8 trash cans with an equal amt. in each,
--> we do 304/8 to find how much baseballs we put in each
=> 304/8 = 38
Now, we takes 5 of these 38 trash cans filled with balls to the field
--> we would do <em>5 x 38 => 5 x 38 = 190</em>
and Thus, we have our answer of <u>190 baseballs</u>
Hope this helps!
