I'm not sure but I think the corresponding angles would be LK and MN, HG and IJ
Scale factor: 21/4= 3

Fully factored form: f(x) = (x − 3)(x + 3)[x − (2 − i)][x − (2 + i)] The function has ____ real roots and ____ imaginary roots.

Lostsunrise [7]

2 real roots and 2 imaginary roots

f(x) = (x - 3)(x + 3 )(x-2 + i)(x - 2 - i)

(x - 3) and (x + 3) give real roots x = ± 3

(x - 2 + i)(x - 2 - i) give 2 imaginary roots x = 2 ± i

Answer: one Apple costs £ 0.20, and one banana costs £ 0.60

Step-by-step explanation:

let x = the amount of apples

let y = the amount of bananas

4x + y = 1.40

7x + y = 2

this is à system of equations

simplify the top equation to y = 1.4 - 4x

now plug that into the second equation and solve

7x + 1.4 - 4x = 2

3x + 1.4 = 2

3x = 0.6

x = 0.2

that means that one Apple costs £ 0.20

plug that back into the top equation

4x + y = 1.4

4(0.2) + y = 1.4

0.8 + y = 1.4

y = 0.6

so one banana costs £ 0.60

A triangle has two angles measuring 69 and 77. Determine the measure of the third angle b

igor_vitrenko [27]

Answer:

$m\angle B=34\°$

Step-by-step explanation:

Given measures of 2 angles of a triangle :

m∠A = 69°

m∠C = 79°

Find m∠B.

We know that sum of angles of a triangle =180°

So, we have

$m\angle A+m\angle B+m\angle C=180\°$

Substituting the vales of m∠A = 69° and m∠C = 79°

$69\°+m\angle B+77\°=180\°$

Adding like terms.

$m\angle B+146\°=180\°$

Subtracting both sides by 146°.

$m\angle B+146\°-146\°=180\°-146\°$

∴ $m\angle B=34\°$ (Answer)

Solve<br> -8- 21 + 10x=61

lozanna [386]

Answer:

Hello! :) I hope I am correct!!

Step-by-step explanation:

The answer would be: x=9

(Below is how I got ‘x=9’)

Here are the steps to solve this problem/equation.

1. Simplify both sides to the equation.

⇒10x +-21=61

⇒10x -29=61

2. Now add 29 to both of the sides

⇒ (you will end up with: 10x=90

3. And finally you divide both sides by 10

⇒ so x=9

Hope this helps!
