Answer:
y = 10, x = 4; each side = 20 units
Step-by-step explanation:
In an equilateral triangle, all the sides & angles are equal to each other. So,
=》AC = AB = BC
=》20 = 2y = 5x
Now,
■ AC = AB
20 = 2y
20/2 = y
10 = y
■ AC = BC
20 = 5x
20/5 = x
4 = x

Solve the equation using the quadratic formula. 262 – 3b+85=-5
Answers
Answer:
b= 352/3
or b= 117.33
Step-by-step explanation:
262-3x+85=-5
-3x+(262+85)=-5
simplify the arithmetic
-3x+347=-5
Group all constants on the right side of the equation
-3x+347=-5
Subtract from both sides:
-3x+347-347=-5-347
Simplify the arithmetic:
-3x=-5-347
-3x=-352
isolate the x
-3x=-352
Divide both sides by -3
-3x/-3}=-352/-3}
Cancel out the negatives
3x/3}=-352/-3
Simplify the fraction
x= -352/-3
Cancel out the negatives
x=352/3

Harrison's Butcher Shop sells 1/3 pounds of bee
for $1.50. If you need to buy 5 pounds of beet
for a cookout, how much would the beef cost?
Setup a proportion to answer the problem.
$27.50
$7.50
$15.00
$22.50
1.50 * 3 = 4.5 (cost 1 pound)
4.5 * 5 = 22.5 (total cost)
The cost of 5 pounds of beef for a cookout given the cost of 1/3 pounds is $22.50
How to find the cost of beef1/3 pounds = $1.505 pounds = $xEquate the ratio
1/3 : 1.50 = 5 : x
1/3 ÷ 1.50 = 5/x

State if each triangle is a right triangle.
Answers
Answer:
Yes.
Step-by-step explanation:
To find if a triangle is a right triangle or not, we use the Pythagorean theorem. The Pythagorean theorem states that [tex]a^{2} + b^{2} = c^{2}[/tex].
a and b are the triangle legs. The c is the hypotenuse of the triangle.
Now, to find if a triangle is a right triangle, we plug in 9 for a and b and 9root2 for c.
[tex]9^{2} + 9^{2} = (9\sqrt{2})^{2}[/tex]
81 + 81 = 81 * 2
162 = 162
So the given triangle, is indeed a right triangle.
Find the co-interior angle measurements for the measured angle.
?
Answers
Answer:
86°
Step-by-step explanation:
As we know that when a transversal intersects two parallel line , then the sum of co-interior angles is 180° . Hence here one of the two co-interior angles is 94° and we are are interested in finding the second one . So , let the unknown angle be x , then ;
[tex]\implies \rm x + 94^\circ = 180^\circ [/tex]
Subtract 94° from both sides,
[tex]\implies \rm x = 180^\circ -94^\circ[/tex]
Simplify,
[tex]\implies \rm \underline{\underline{x = 86^\circ}}[/tex]
Hence the required answer is 86°

-The dimensions of a rectangular garden were 2 m by 4 m. Each dimension was
Increased by the same amount. The garden then had an area of 48 m2. Find the
dimensions of the new garden. (Hint: let x be the amount of increase.)
Answers
Answer: 4 m
Step-by-step explanation:
Let the amount each dimension was increased by be x.
Now we can set up a equation.
(2+x)(4+x) = 48
8 + 2x + 4x + x^2 = 48
x^2 + 6x - 40 = 0.
We can factor the left side of the equation.
(x+10)(x-4) = 0.
Therefore, x equals either -10 or 4. Since you can't increase a dimension by a negative amount, x must equal to 4.

find (f-g)(x) for f(x)=x^2+8x and g(x)=3x-5
Answers
Answer:
(f-g)(x)= f(x) - g(x)
= x^2 + 8x - ( 3x - 5)
= x^2 + 8x - 3x + 5
= x^2 + 5x + 5
(f-g)(x)= x^2 + 5x + 5
The required expression of (f-g)(x) = x^2+5x+5.
f(x) = X^2+8x; g(x) = 3x - 5
(f-g)(x) to determine.
It is defined as the number of composition, constitute the whole.
Here, (f-g)(x)= f(x)-g(x)
= x^2+8x-3x+5
= x^2 + 5x + 5
Thus, the required expression of (f-g)(x) = x^2+5x+5.
