7.1 is the value of Ef where cd=df

Answer:

7.1 units.

Step-by-step explanation:

It is given that cd is congruent to df, e bisects df and cd= 14.2.

We have to find the measure of ef.

Using given information we get

cd\cong df

cd=df=14.2             (Measure of congruent segments are equal)  ... (1)

de=ef=\dfrac{df}{2}   (e bisects df)      ... (2)

Using (1) and (2) we get

ef=\dfrac{14.2}{2}

ef=7.1

Hence, the measure of ef is 7.1 units.

Which shows the correct substitution of the values a, b, and c from the equation 0 = – 3x2 – 2x + 6 into the quadratic formula?
lbvjy [14]

Answer:

x = StartFraction negative

(negative 2) plus or minus StartRoot (negative 2) squared minus 4 (negative 3)(6) EndRoot Over 2(negative 3) EndFraction

Step-by-step explanation:

0 = – 3x2 – 2x + 6

It can still be written as

– 3x2 – 2x + 6 =0

Quadratic formula=

-b+or-√b^2-4ac/2a

Where

a=-3

b=-2

c=6

x= -(-2)+ or-√(-2)^2-4(-3)(6)/2(-3)

x = StartFraction negative

(negative 2) plus or minus StartRoot (negative 2) squared minus 4 (negative 3)(6) EndRoot Over 2(negative 3) EndFraction

I need help with the following question, whichever one is right will get brainliest!
Schach [20]

Given: m∠A + m∠B = 90° (Definition of Complementary Angles).

Given: m∠B = (5x + 8)°

A) m∠A = 180° + (5x + 8) is your answer choice:

Why it isn't the others:

B) m∠A = 90° - (5x + 8)

You are solving for complementary angles (90° in total when combined), so you subtract the measurement for B (5x + 8) to get A.

C) m∠A = 180° - 2(5x + 8)°

You double the complementary angle to solve for the supplementary. Essentially, just divide this answer by two to get the complementary angles.

D) m∠A = 82 - 5x

I was confused by this one, but essentially they just did one step of the isolating the variable, which was subtracting 8 from both sides. They did not finish isolating the variable however.

Find value of x In x^2+2x
lara [203]

Answer:

See explanation

Step-by-step explanation:

Assuming we want to solve for x in:

{x}^{2}  + 2x = 0

Then we factor to get:

x(x + 2) = 0

Apply the zero product principle to get:

x = 0 \: or \: x + 2 = 0

x = 0 \: or \: x =  - 2

The question is not all that clear, so I assume you are solving for x in the completed quadratic equation.
