Books are rectangles so that means that opposite sides are equal so if one side is 10 inches then so is the opposite side. same for the 8. the perimeter is the amount around the rectangle so you must add all sides together to find it so
10in+10in+8in+8in= 36in
Answer:
160 pages.
Step-by-step explanation:
That is 125 - 0.20 * 125
= 125 - 25
= 160 pages.
Answer:
A.
<em>Brainliest, please!</em>
Step-by-step explanation:
In order to prove two triangles similar by AA, two angles in one triangle must be congruent to the opposite angles in the other. A is the only option that works as B and C are sides, which aren't relevant, and D, while an angle, doesn't make sense.
Answer:
x = 3.5 is not a solution
Step-by-step explanation:
3x +2 < 12
Subtract 2 from each side
3x +2-2 < 12-2
3x< 10
Divide each side by 3
3x/3 <10/3
x < 10/3
x <3.3333333
Any number greater than 3.3333 is not a solutions
3.5 is not a solution
You can multiply or divide one equation so that it has a variable with a coefficient opposite of the other equation.
Example:
A) 2x + 3y = 6
B) 4x +2y = 20
Notice that neither equation has a "1" or "-1"
Let's multiply Equation A) by -2
A) -4x -6y = -12 Then add it to B)
B) 4x +2y = 20
-4y = 8
y= -2
A) 2x + 3*-2 = 6
2x = 12
x = 6
