I'll solve one from each kind

Q1)

6 = a/4 + 2 <em>(mutiply both sides)</em>

24 = a + 8 <em>(move the terms)</em>

-a = 8 - 24 <em>(calculate)</em>

-a = 8 - 16 <em>(change the signs)</em>

a = 16

Q8)

2( 2 + 5) = -2 <em>(divide both sides)</em>

n + 5 = -1 <em>(move the constant to the right)</em>

n = -1 - 5<em> (calculate)</em>

n= -6

Q3)

9x - 7 = 7 <em>(cancel equal terms)</em>

9x = 0 <em>(divide both sides)</em>

x = 0

Help please I don’t understand it
Jlenok [28]

Answer:

15) 30

16) 2

for 15 you plug the -4 into the variable (x)

so...

-4(-4)-4-2-5(-4)

you do multiplication first because of PEMDAS

so -4×-4=16 it is not negative because there 2 negatives so they cancel out

then -5×-4=20

then you get this:

16-4-2+20 which equals 30

then with 16 you do the same. you just put the number for y in the variable y and same with x

I have a test on the Pythagorean theorem and dilations on Monday...for dilations could you plz help me understand it and how to
lesantik [10]
The Pythagorean theorem states that a² + b²= c². this theorem only works with RIGHT TRIANGLES, and thats all.

i don't think dilations has a formula, unless you count the scale factor as its formula.
