Solution to x^2+2x+4=0

1 answer:

4 0

${x}^{2} + 2x + 4 = 0 \\ \Leftrightarrow {x}^{2} + 2x + 1 = - 4 + 1 \\ \Leftrightarrow \underbrace{ {(x + 1)}^{2} }_{ \geqslant 0} = - 3 \\ \Leftrightarrow x\in\emptyset$

Which congruence criteria can be used directly from the information about triangles HIJ and MNO to prove IJ¯¯¯¯¯¯≅MN¯¯¯¯¯¯¯¯¯¯ b

skelet666 [1.2K]

Answer: $\overline{IJ}\cong \overline{MN}$

Step-by-step explanation:

Given: In triangle HIJ and triangle MNO we have

$\overline{HI}\cong \overline{NO}, \angle{I}\cong \angle{N} ,\angle{H}\cong \angle{O}$

here, HI and NN are the included side between ∠I & ∠H and ∠N and ∠O.

So , by ASA congruence rule,

ΔHIJ ≅ ΔMNO

So by CPCTC (corresponding parts of the congruent triangles are congruent)

$\overline{IJ}\cong \overline{MN}$

Jodi's car used 12 gallons of gas to travel 456 miles. How many miles did her car travel per gallon of gas? Show your work. Answ

Sloan [31]

Answer:

The number of miles her car travel per gallon of gas is 38 miles per 1 gallon of gas

Step-by-step explanation:

Given

Size of Gas = 12 gallon of gas

Distance = 456 miles

Calculating the number of miles her car travel per gallon of gas.

This in calculated by distance/size of gas

By substituton, it becomes

Number of miles = 456 miles/12 gallons ------ divide

Number of miles = 38 miles / gallon.

Hence, the number of miles her car travel per gallon of gas is 38 miles per 1 gallon of gas

How to find the axis of symmetry if the parabola doesn't cross the y axis<br> please i need help

ale4655 [162]

Step-by-step explanation:

a parabolic graph is given by the equation ax^2 + bx + c

the axis of symmetry is equal to -b/(2a)

however it is worth noting that all parabolas have a y intercept since their domain is all real numbers.

make sure to inform me if you need further guidance.
