Do you have a picture of the question? From what I can tell if both question marks represent the same number, the answer is -3.125 but I’d hate be be overthinking a more simple question. Here’s my work but if I looks too confusing it probably is and I read the question wrong
Answer: 20 feet
Step-by-step explanation:
This represents a right angled triangle with the length of the slide being the hypotenuse, the height of the ladder being the height of the triangle and the distance from the base of the ladder being the length.
Solve with Pythagoras rule:
c² = a² + b²
c = hypotenuse
a= length
b = height
29² = 21² + b²
841 = 441 + b²
b² = 841 - 441
b² = 400
b = √400
b = 20 feet
I think this is the answer you are looking for
A linear equations is y= mx+b
m=slope
b= y- intercept, to help me think of what b is I try to figure out where a point is on the y axis so (0,x) that would be your point on the y- axis
:) hope this helps, if you have any questions please ask
<h3><u>Given</u> :</h3>
- 2x²y - 4xy², x = - 1 & y = 1
<h3><u>To Find</u><u> </u> :</h3>
<h3><u>Solution</u> :</h3>
2x²y - 4xy²
<u>Substituting the value of x & y</u>,
= 2(- 1)² × 1 - 4(- 1) × 1²
= 2 × 1 × 1 + 4 × 1
= 2 + 4
= 6
<u>Hence, The value of the expression is 6</u>.
