Answer:
True
Step-by-step explanation:
Each x input has 1 y output
This question boils down to this:
"What is the diagonal of a square with a side length of 90 ft?"
The key to this question is the properties of squares.
All of the angles in a square are right, (90°) but that diagonal is going to bisect two of those into 45° angles.
Now we have two triangles, each with angle measures of 45°, 45°. and 90°.
(an isoceles right triangle)
This 45-45-90 tirnalge is one of two special triangles (the other being the 30-60-90) and here is its special property: the sides opposite these angles can be put as x, x, and x√2 respectively. Why? Well, we know that our triangle is isoceles (the congruent base angles ⇔ congruent sides) and so we call those x...by the Pythagorean theorem...a² + b² = c²...2x² = c²...x√2 = c!
In our case here, that diagonal, being the hypotenuse of our triangle, is going to be 90√2 feet, or approximately 127.3 feet.
The answer is C.)
S1 = 600 (divide by 2)
S2 = 300 (divide by 2)
S3 = 150 (divide by 2)
S4 = 75 (divide by 2)
S5 = 37.5
Answer:
P = 2n + 8m - 1
Step-by-step explanation:
A <u>trinomial is an expression or equation that has three terms</u>. A term is when between the numbers or variables, the operations are neither subtraction nor addition, or when there is only one number.
If two terms have the <u>same variable</u>, called <u>like terms</u>, they can be combined by addition or subtraction.
The perimeter is the total length of all the sides.
The formula for the perimeter of a triangle is 
for each of the three sides.
Substitute each of the three sides.
brackets can be removed
rearrange equation according to like terms
collected the like terms by addition
Answer:
C
Step-by-step explanation:
y = (2x - 2) / 4 Interchange x and y
x = (2y - 2) / 4 Multiply both sides by 4
4x = 2y - 2 Add 2 to both sides.
4x + 2 = 2y Divide both sides by 2
4x/2 + 2/2 = 2y / 2
2x + 1 = y
Now put 3 in wherever you see an x
2*3 + 1 = y
6 + 1 = y
7 = y
