Answer:
x = -7
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−5(x−1)=40
(−5)(x)+(−5)(−1)=40(Distribute)
−5x+5=40
Step 2: Subtract 5 from both sides.
−5x+5−5=40−5
−5x=35
Step 3: Divide both sides by -5.
−5x/−5 = 35/−5
Answer:
x = -7

Answer:
43b. (-1, 2)
43a. (1, -3)
36b. Yes: (0,9)
Step-by-step explanation:
<u>43b</u>. x+y=1
-x+y=3
----------------------
2y=4 > y=2
2+x=1 > x=-1
check:
2(-1)+2=0
0=0
<u>43a</u>. can you figure this one out by yourself and then check it? If you can't I will show my work. The answer is above. :)
<u>36b</u>. y-(0)^2=9
y=9
Answer:
The answer is mostl likely A.
Hope this helps
Let length of shortest side be x
then length of each congruent sides = x + 1
perimeter of the triangle = x + x+1 +x + 1 = 3x + 2
perimeter of the square = 4(x-2) = 4x - 8
So we have
4x - 8 = 3x + 2
x = 10
the shortest side is 10 units long.
Answer:
Step-by-step explanation:
l = Length = 11 cm
w = Width = 8 cm
h = Height = 8 cm
