Answer:
Area=32 square inches
Step-by-step explanation:
<em>Step 1: Determine the dimensions of the rectangle</em>
Width=w
Length=2×w=2 w
<em>Step 2: Determine the perimeter of the rectangle</em>
P=2(L+W)
where;
P=perimeter
L=length
W=width
In our case;
P=24 inches
W=w
L=2 w
replacing;
2(w+2 w)=24
2(3 w)=24
6 w=24
w=24/6=4
The width of the rectangle=4 inches
The length of the rectangle=2×4=8 inches
<em>Step 3: Determine the Area of the rectangle</em>
Area=length×width
where;
length=8 inches
width=4 inches
Area=8×4=32 square inches
Answer:
B
Step-by-step explanation:
8 x 8 = 64
Answer: 8.01
Step-by-step explanation:
Speed = distance/time = 280/4.5 = 62.44mph
Time = distance/speed = 500/62.44 = 8.0071 hrs
(8x + 7) - (2x - 3)
(8x + 7) + (-2x + 3)
combine like terms
8x - 2x and 7 + 3
6x + 10
Answer:
Step-by-step explanation:
y - 3x = 18
To find the y- intercept let x = 0 in the equation and solve for y
y - 3(0) = 18
y - 0 = 18
y = 18 ⇒ (0,18 ) ← y - intercept
To find the x- intercept let y = 0 in the equation and solve for x
0 - 3x = 18
- 3x = 18 ( divide both sides by - 3 )
x = - 6 ⇒ (- 6, 0 ) ← x- intercept
