Answer:
see below
Step-by-step explanation:
1) 6(x + 1)+ 5 = 35
Distribute
6x+6 +5 = 35
Combine like terms
6x+11 =35
Subtract 11
6x+11-11=35-11
6x = 24
Divide by 6
6x/6 =24/6
x = 4
2) 0.7(x - 2) = 0.3
Distribute
.7x -1.4 = .3
Add 1.4 to each side
.7x-1.4+1.4 = .3+1.4
.7x = 1.7
Divide each side by .7
.7x/.7 = 1.7/.7
x = 17/7 = 2.482571429
3) 7(4x + 9) - 13 = 87
Distribute
28x +63 -13 = 87
Combine like terms
28x +50 = 87
Subtract 50 from each side
28x +50-50 =87-50
28x=37
Divide each side by 28
28x/28 = 37/28
x = 37/28 = 1 9/28
4) 0.25(3 - x) = 0.375
Distribute
.75 -.25x = .375
Subtract .75 from each side
.75-.75 -.25x = .375-.75
-.25x = -.375
Divide each side by -.25
-.25x/-.25 = -.375/-.25
x =1.5
Answer:
c is totally the corrects answer because non of the become nagative and your welcome plz give brainliest if im wrong then it is d
Step-by-step explanation:
Answer:
x^2+2xy+y^2
Step-by-step explanation:
(x + y)(x + y)
FOIL
first x*x = x^2
Outer x*y = xy
inner: y*x = xy
last y*y = y^2
add together
x^2+xy+xy+y^2
Combine like terms
x^2+2xy+y^2
8. hope this helps. If don't ill edit and try to see the right answer. bye ;)
see what should to do buddy :
step 1-
first we have to find the gradient of the line like this:
a ( 1 , 1 )
b ( 3 , 4 )
.
step 2-
now just need one of the a or b point to put in this equation :
.
step 3-
to find the standard form of the line we have to take the y alone.
so we add the sides of the equation plus 1.
And we're done.
good luck buddy ♥️♥️♥️♥️♥️
