Answer:

a=120

b=240

Step-by-step explanation:

if x=12

a=5×2×2×2(x-5)

5×2=10×2×2=40

40(x-5) 40x-200

200=40×\40x=5

b=2×10×12=240

a=120

b=240

Answer:

y = 15

Step-by-step explanation:

In a parallelogram, opposite lengths are equal.

So it means that the length (5y - 20) is equal to (2y + 25).

Now that there is only one variable in the equation, we can solve for the variable.

5y - 20 = 2y + 25

5y - 2y = 25 + 20

3y = 35

y = 15

F(x)=(2x-1)(x-5) find all zeros
Sergio039 [100]

Answer:

x = 5 and x = \frac{1}{2}

Step-by-step explanation:

To find the zeros equate f(x) to zero, that is

(2x - 1)(x - 5) = 0

equate each factor to zero and solve for x

2x - 1 = 0 ⇒ x = \frac{1}{2}

x - 5 = 0 ⇒ x = 5
