Let x be the original side length of the square
P=2(l+w)
70=2((2.5+x)+(2.5+x))
70=2(5+2x)
70/2 = 5+2x
35-5=2x
30=2x
15=x
Therefore, the original length of the square was 15"
Hope I helped :)
Answer:
(a) II 1/1, 1/2, 1/3, 1/4, 1/5 I 2/1, 2/2, 2/3, 2/4, 2/5 I 3/1, 3/2, 3/3, 3/4, 3/5 I 4/1, 4/2, 4/3, 4/4, 4/5 I 5/1, 5/2, 5/3, 5/4, 5/5 II
(b) 9/25
(c) You would expect 2 more because 9 out of 25 you should get a 4, and the math is, 100 / 24 = 4 I 9 x 4 = 36.
Step-by-step explanation:
I took the K12 test, and don't copy paste this answer pls.
Answer:
14 and simplify to 4
Step-by-step explanation:
Add 1010 to both sides.
x=4+10
x=4+10
2 Simplify 4+104+10 to 1414.
x=14
x=14
x−10=4
1 Let x=14x=14.
14-10=4
14−10=4
2 Simplify 14-1014−10 to 44.
4=4
4=4
The sum of the squares of the lengths is 58
The square of length of the hypotenuse is 58
From the question, we have
AB² = (-2-3)² +(7-5)²= 25+4 =29
BC² = (3-1)²+(5-0)²=4+25=29
AC² = (-2-1)²+(7-0)² = 9+49 = 58
Here we can see that,
AB²+BC² = AC²
The sum of the squares of the lengths of two sides (the legs) equals the square length of the third side (hypotenuse).
the sum of the squares of the lengths = AB²+BC² =29+29 = 58
the square of length of the hypotenuse= 58
Pythagoras Theorem:
In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem. These triangle's three sides are known as the Perpendicular, Base, and Hypotenuse. Due to its position opposite the 90° angle, the hypotenuse in this case is the longest side. When the positive integer sides of a right triangle (let's say sides a, b, and c) are squared, the result is an equation known as a Pythagorean triple.

To know the unit of measurement of the final answer, you have to use the technique of dimensional analysis. In this technique, you strip off the magnitudes of the units to do away with the calculations. You have to make sure first that you end up with the final answer. So, for this problem, you are given two parameters: force and surface area. Thus, you focus on the units of force and surface area. One of the units must be in Newtons to represent the force, and the other should be in square units to represent the area. From the choices given, the answer would most likely be letter B.
This is the other choices include units like cubic units and kilograms which pertain to volume and mass, respectively. None of these have to do with force and surface area.
