BRAINLIEST!!! (Please help)

Mathematics
1 answer:
IrinaK [193]3 years ago
8 0

Answer:

A

Step-by-step explanation:

- to find x we use tan 60 = x/7

- rearrange, tan60*7 = x, x = 7\sqrt{3}

- now you have two sides so you can use pythagoras  to find z

y^2 + x^2 = z^2

z = \sqrt{(7\sqrt{3})^2 + (7)^2 }

z = 14

Jackson used the process of completing the square to solve the equation 2x2−12x=−6.
Nikolay [14]

Answer:

x=3-\sqrt{6},x=3+\sqrt{6}

Step-by-step explanation:

we are given equation as

2x^2-12x=-6

Since, we have to solve it by using complete square

so, firstly we will complete square

and then we can solve for x

step-1:

Factor 2 from both sides

2(x^2-6x)=-3\times 2

step-2:

Simplify it

x^2-6x=-3

step-3:

Add both sides 3^2

x^2-6x+3^2=-3+3^2

now, we can complete square

(x-3)^2=6

step-4:

Take sqrt both sides

(x-3)=-\sqrt{6},(x-3)=\sqrt{6}

step-5:

Add both sides by 3

we get

x=3-\sqrt{6},x=3+\sqrt{6}
