The expression that we need to get is:
So the correct option is the second one.
<h3>Which expression gives the number of gallons of stain Bradley will need?</h3>
We know that 1 gallon is enough to cover 200 ft².
We have two rectangular areas, one of:
23 feet by 10.4 feet, and other of 10.5 feet by 7.2 feet.
Then the total area is:
A = (23 ft)*(10.4 ft) + (10.5ft)*(7.2 ft)
The number of gallons needed is given by the quotient between the area that we want to cover, and the area that covers one gallon, so the expression is:
So the corerect option is the second one.

The answer is 42,84,126 and so on.(you keep on adding 42)
Answer:
x = 1 or x = −6
Step-by-step explanation:
Step 1: Subtract 18 from both sides.
3x2+15x−18=18−18
3x2+15x−18=0
Step 2: Factor left side of equation.
3(x−1)(x+6)=0
Step 3: Set factors equal to 0.
x−1=0 or x+6=0
x=1 or x=−6

DTBC is a rhombus
<RTB = <FCB
Find
RD = DF
Solution
- <RTB = <FCB Given
- TD = DC Property of a Rhombus (all four sides are equal)
- <RDT = <FDC Vertically opposite angles are equal
- ΔRDT ≅ ΔFDC Δ = triangle. The Δs are congruent by ASA.
- RD = DF Parts of congruent triangles are congruent.
You will get problems like the way you were trying to do it. But you should just mark out what you know. I think that you might have forgotten about vertically opposite angles.
