Answer:
X=65°
Step-by-step explanation:
Both angles combined is a right angle as indicated by the small square drawn on it, a right angle is always 90° therefore
(x-15°)+40°=90°
combine like terms
x+25°=90°
subtract 25° from each side
x=65°
Let's solve your equation step-by-step.
<span><span><span><span>3v</span>+9</span>−<span>8v</span></span>=<span>−31
</span></span>Step 1: Simplify both sides of the equation.
<span><span><span>−<span>5v</span></span>+9</span>=<span>−31
</span></span>Step 2: Subtract 9 from both sides.
<span><span><span><span>−<span>5v</span></span>+9</span>−9</span>=<span><span>−31</span>−9</span></span><span><span>−<span>5v</span></span>=<span>−40
</span></span>Step 3: Divide both sides by -5.
<span><span><span>−<span>5v</span></span><span>−5</span></span>=<span><span>−40</span><span>−5
</span></span></span><span>v=<span>8</span></span>
Answer:
Addition POE
Step-by-step explanation:
I believe it is the addition POE because
12x-4=44
To get 4 (the constant) to the right you have to do the inverse of subtraction which is addition. By doing so You would add 4 to both side, canceling it out on the left side and adding the 4 to the right side (44).
12x-4=44
<u> +4 +4</u>
12x=48
12/12=48/12
x=4
Just flip your fraction around and your answer will be 10/11
(x-6)(x+6)
solve just to make sure
x^2+6x-6x-36
combine like terms
x^2-36
