Area is trapezium =
A=1/2h(a+b)
84=1/2(6)(7+b)
84=3(7+b)
84=21+3b
3b=84-21
B=63/3
B= 21 cm
I’m sorry if my answer turned out to be wrong but I tried my best so best of luck !!
Answer:
k = 1
Step-by-step explanation:
=> y ∝ x²
So, y = kx² ----------------------------(1)
<u><em>Where k is the constant of proportionality</em></u>
Now,
y = 9 when x = 3
Putting in (1)
=> 9 = k(3)²
=> 9 = k(9)
Dividing both sides by 9
=> k = 1

Let's solve your equation step-by-step.
4(a+4)−2=34
Step 1: Simplify both sides of the equation.
4(a+4)−2=34
(4)(a)+(4)(4)+−2=34 (Distribute)
4a+16+−2=34
(4a)+(16+−2)=34 (Combine Like Terms)
4a+14=34
4a+14=34
Step 2: Subtract 14 from both sides.
4a+14−14=34−14
4a=20
Step 3: Divide both sides by 4.
