Answer: (5a+b)/2
Step-by-step explanation:
1. First factor 5a^2+36ab+7b^2
=(5a+b)(a+7b)
2. Factor 2a+14b
The two can be factored out, making the equation equal to 2(a+7b).
The factored out equation is now [tex]\frac{(5a+b)(a+7b)}{2(a+7b)}[/tex]
Since there is an (a+7b) on both sides of the fraction, they cancel out. You are left with (5a+b)/2. This fraction cannot be simplified more.
To verify you can multiply (5a+b)/2 times (2a+14b). If it is correct, it should come back out as 5a^2 + 36ab +7b^2

ill give the brainliest to the correct and the best explained answer :))
Answer:
20 m
Step-by-step explanation:
Using the Pythagorean Theorem,
a² + b² = c²
c² = (16)² + (12)²
= 256 + 144
= 400
c =√400
c = 20 m
Solution:
Given:
Length of rectangle = 16 mBreadth of rectangle = 12 mSolve using Pythagoras theorem:
c (Diagonal)² = 12² + 16²=> c² = 144 + 256=> c² = 400=> c = √400 = 20 mThere are a 11 of birds on a fence between person named ben had the license to hunt animals he shot one bird how many would there be and also how many was there?

Oliver earns $45 per week mowing lawns in his
neighborhood. Which expression can be used to
show how much money he earns in 8 weeks??
A. (8 x 40) + (8 x 5)
B. (8 x 40) x (8+5)
C. (8 + 40) x (8 + 5)
D. (8 + 40) + (8 x 5)
This scale drawing shows a.reduction in a figure what is the value of X
Answer:
x = 2.25
Step-by-step explanation:
8:6
So, 8/6 = 4/3 or 1.33333333 (decimal multiplier)
Therefore, 8 divided by 4/3 = 6.
Then, we could also do 3 divided by 4/3= 9/4 or 2.25.
2.25 x 4/3 = 3.
Answer:
x = 2.25
setting up proportionality:
[tex]\rightarrow \sf \dfrac{8}{3} = \dfrac{6}{x}[/tex]
[tex]\rightarrow \sf 8x = 18[/tex]
[tex]\rightarrow \sf x = \dfrac{18}{8}[/tex]
[tex]\rightarrow \sf x = 2.25[/tex]
Below are two regular polygons. Calculate the value of angle a.
If the length of the base of both triangles measures 80 inches, what is the length of the kite’s shorter diagonal? 30 inches 39 inches 10 StartRoot 39 EndRoot inches 10 StartRoot 11 EndRoot inches.
The length of kite’s shorter diagonal is 39 inches.
What is a KiteA kite is a quadrilateral (has four sides and four angles) in which adjacent sides are congruent and the diagonal bisect at 90 degrees.
Each leg of the upper triangle measures 41 inches and each leg of the lower one measures 50 inches. Hence half the length of the base = 80/2 = 40. The base = diagonal = 80 inches
Using Pythagoras:
41² = d₁² + 40²
d₁ = 9 inches
Also:
50² = d₂² + 40²
d₂ = 30 inches
Length of diagonal = 9 + 30 = 39 inches
The length of kite’s shorter diagonal is 39 inches.

This is a special type of triangle known as a 45-45-90 triangle.
The ratio for the sides of this triangle are x:x:x[tex]\sqrt{2}[/tex]
Meaning that the two sides other than the hypotenuse are equal, so in this triangle x=9 because it is not a hypotenuse.
The hypotenuse, however, is the value of one side multiplied by [tex]\sqrt{2}[/tex].
In this case it is 9, so 9*[tex]\sqrt{2}[/tex] = [tex]9\sqrt{2}[/tex]
