Looks like distributive property 5 times 5 is 25, 5 times a -5i is -25i , 5i times 5 is positive 25i , 5i times 5i gives you , 25 i squared , so now you combine like terms , you have 25 -25i + 25i - 25i squared , cross out -25i and the positive 25i anf your left with 25-25 squared .

Solve for m

MakcuM [25]

Answer:

m = 29/48

Step-by-step explanation:

Given that

x₂ = (y₂-y₁) +10 →(1

y₂ = y₁-x₁ → (2

y₁= 37

x₁ = 29

Now substitute the value of x₁ and y₁ into equation 2

y₂ = 37-29

y₂ = 8

Now substitute the value of y₂ and y₁ into equation 1

x₂ = (8-37) +10

x₂ = -19

As we know the slope (m) can be calculated as follows

m =(y₂ - y₁)/(x₂ - x₁)

m = (8- 37)/(-19 - 29)

m = (-29)/(-48)

m = 29/48

So our slope is 29/48

I quite don’t get this question and I have 4 minutes remaining

The length of one of the sides of the larger pentagon is 24 cm. The length of one of the sides of the smaller pentagon is 8 cm.

$24$ ÷ $8=3$

So, if the larger pentagon is 3x the size of the smaller pentagon, we can find the area of the smaller pentagon by dividing the area of the larger pentagon by 3.

$135$ ÷ $3=45$

The area of the smaller pentagon is 45in²

Hope this helps! Pwease mark me brainliest! Have a great day!

Given f(x)=x^2-4x+5, what's the value when f(2)

Reil [10]

If you were to replace the x's with 2, your equation would turn into:

(2)^2-4(2)+5

From there, you'd just solve.

4-8+5=1

Your answer would be 1.
