Answer:
r = 24
Step-by-step explanation:
3(r+2)+5(2−r)=−32
Step 1: Simplify both sides of the equation.
3(r+2)+5(2−r)=−32
(3)(r)+(3)(2)+(5)(2)+(5)(−r)=−32(Distribute)
3r+6+10+−5r=−32
(3r+−5r)+(6+10)=−32(Combine Like Terms)
−2r+16=−32
−2r+16=−32
Step 2: Subtract 16 from both sides.
−2r+16−16=−32−16
−2r=−48
Step 3: Divide both sides by -2.
−2r/-2 = -48/-2
r = 24
Here, trapezoid is composed of two triangles, and one rectangle.
So, Area of rectangle = 4 * 7 = 28 cm²
Area of a triangle = 1/2 * 3 * 7 = 21/2 = 10.5 cm²
Area of Trapezoid = area of rectangle + 2(area of triangle)
= 28 + 2(10.5)
= 28 + 21 = 49
In short, Your Answer would be 49 cm²
Hope this helps!

Answer:
A
Step-by-step explanation:
5 (-5 + n) = -3 - 6n
-25 + 5n = -3 - 6n
-25 + 11n = -3
11n = 22
n = 2
Answer: -13w - 7
Step-by-step explanation:
-6w + (-8) + 1 + (-7w)
Combine the like terms
-8 + 1 = -7
-6w + (-7) + (-7w)
-6w + (-7w) = -13w
-13w + (-7)
However, because adding a negative number is the same as subtracting the number as a positive, you can just make it -13w - 7
