The formula to find surface area is SA= 2(L×W + L×H + H×W)
The 2 is there to double each side.
so..
A)
SA = 2(L×W + L×H + H×W)
= 2( 16×9 + 16×4 + 4×9)
= 2( 144 + 64 + 36)
= 2( 244)
= 488 units2
B) SA = 2(L×W + L×H + H×W)
= 2 ( 13×9 + 13×4 + 4×9)
=2 ( 117 + 52 + 36)
=2 ( 205)
SA= 410cm2
Answer:
Marie's bucket holds the least amount of water.
Step-by-step explanation:
Sammy's bucket holds 2.53 liters of water. (2530 / 1000 = 2.530)
Marie's bucket holds 2.03 liters of water. (2 + 0.030 = 2.030)
Katie's bucket holds 2.35 liters of water. (2 + 0.350 = 2.350)
If you compare all these values, 2.03 is the least out of all of them.
4.4 + (4 × 14 + 8.6)
Follow the order of operations (PEMDAS).
4.4+(56+8.6)
4.4+(64.6)
answer: 69
Answer:
x=7 multiplicity of 2
Step-by-step explanation:
14x - 49 = x^2
Subtract x^2 from each side
-x^2 +14x - 49 = x^2-x^2
-x^2 +14x - 49 = 0
Multiply by -1
x^2 -14x +49 =0
What 2 numbers multiply together to give you 49 and add together to give you -14
7*-7 = 49
-7+-7 = -14
(x-7) (x-7) = 0
Using the zero product property
x-7 = 0 x-7 =0
x-7+7= 0+7 x-7+7 =0+7
x =7 x=7
