Answer:
lINEAR
Step-by-step explanation:
The right triangle has legs of x and 2.5 where x is the height up the wall that the ladder will reach. The length of the ladder is the hypotenuse of the right triangle.
According to the Pythagorean Theorem, x^2 + 2.5^2 = 12^2
x = 11.736 approx To the nearest tenth that is 11.7.
Answer:
x=-5
Step-by-step explanation:
25-3x=40
-3x=40-25 (both side -25)
-3x=15 (both side divide by 3)
x=5

Answer:
u = -3
Step-by-step explanation:
Step 1: Write equation
-4 + 2u = -10
Step 2: Solve for <em>u</em>
<u>Add 4 to both sides:</u> 2u = -6
<u>Divide both sides by 2:</u> u = -3
Step 3: Check
<em>Plug in x to verify if it's a solution.</em>
-4 + 2(-3) = -10
-4 - 6 = -10
-10 = -10
