Answer:
Area = (a² -5a) in²
Perimeter = (4a -10) in
Step-by-step explanation:
Let the length of the rectangle be a.
Given that, its width is 5 in less than the length.
So,
length ⇒ a
width ⇒ (a - 5)
First, let's find the area of the rectangle.
Area = length × width
Area = a ( a - 5 )
<em>Solve the brackets.</em>
Area = <u>(a² -5a) in²</u>
<u />
Now, let us find the perimeter of the rectangle.
Perimeter = 2 ( l + w )
Perimeter = 2 ( a + a - 5 )
Perimeter = 2 ( 2a - 5 )
Perimeter = <u>(4a -10) in</u>
X-intercept is when y=0;
4x-3(0)=12.3
4x=12.3
x=12.3/4
x=3.075 (x-intercept)
y-intercept is when x=0
4(0)-3y=12.3
-3y=12.3
y=12.3/-3
y=-4.1 (y-intercept)
Hope I helped :)
Answer:
2 9/12 and 2 11/12
Step-by-step explanation:
if that is what u are asking. simplist form is 2 3/4 and 2 11/12.
Hope that helps and good luck :)
Y - y₁ = m(x -x₁)
slope m = -2, from point (10, -9) , x₁ = 10, y₁ = -9
y - y₁ = m(x -x<span>₁)
</span>y - -9 = -2(x - 10<span>)</span><span>
y + 9 = -2(x - 10) </span>
c + 2c = 33
3c=33 (now divide by 3 both sides of equation)
c=11
so Ann has 11 apples (c=11) and her brother has 22 apples (2c=2×11=22)
