Answer:
t=sqrt(41)/4
Step-by-step explanation:
h=-16t^2+41, h=0. -16t^2+41=0, t=sqrt(41)/4
Answer:
x=4
Step-by-step explanation:
The first thing you need to do is combine like terms which would give you
3x-4=8 then you would add four to both sides giving you 3x=12 finally you would divide both sides by 3 giving you x=4.
Answer:
A = (x + 25)(x + 15) - 30
Step-by-step explanation:
This question is not complete without a figure; find the figure attached.
Marissa is painting a regular patio with dimensions as
Length = (x + 25) units
Width = (x + 15) units
Area of this rectangular patio = Length × Width
Area = (x + 25)(x + 15) unit²
She has to paint the patio except the bench that does not need to be painted.
Dimensions of the rectangular bench,
Length = 10 units
Width = 3 units
Area of the bench = 10×3 = 30 units²
Area of the patio to be painted = Area of patio - Area of bench
A = (x + 25)(x + 15) - 30
