x=4/7
Step-by-step explanation:
get x alone.
1st get 3 on the other side of the = sign by using the opposite sign. the opposite of addition is subtraction
-5x+3=2x-1
-3 -3
-5x=2x-1-3
-5x=2x-4
now we get the xs together. the opposite of addition( the 2 is positive) is subtraction
-5x=2x-4
-2x -2x
-7x=-4
now let's get the -7 out of here. -7 is multiplying by x. the opposite of multiplication is division.
<u>-7x</u><u> </u>= <u>-</u><u>4</u>
-7. -7
x=-4/-7
negative divided by a negative is a positive
x=4/7

Hello,
To solve, factour out the expression: <span>9a^4b^4-27a^3b^3+18a^3b^2.
Once factoured out you get the GCF 9a^(3)b^(2)

Answer:
Step-by-step explanation:
In order to solve for this equation we have to note a couple of things.
There is a diagonal square inside a larger square. The space formed by the smaller square not being in the larger square is a right triangle.
The side length of the smaller square (4) is also the hypotenuse of this triangle.
Since we know that the other side length of the triangle is 3, we can use the Pythagorean Theorem to find the value of b.
The Pythagorean Theorem states that 
, where a and b are the legs and c is the hypotenuse.
We can substitute 3 in as a and 4 in as c and find b.
So b is 
units long.
Hope this helped!
on number 5 question the answer is 4,5,9
Step-by-step explanation:
it is because a right triangle is composed of 3 different sides (hypothenus, opposite angle and adjacent angle)
