Answer:

x = 2

Step-by-step explanation:

7(3x + 5) - x = 75

1. Distributive property

multiply 7 by whatever is in the parenthesis

7*3x + 7*5 - x = 75

21x + 35 - x = 75

2. Combine like terms

21x - x = 20x

20x + 35 = 75

3. Subtract 35 on both sides

20x + 35 - 35 = 75 - 35

20x = 40

4. Divide both sides by 20 since u want to isolate the variable

20x/20 = 40/20

x = 2

And thats ur answer

Hope this helped!

Answer:

f(11) = 9

Step-by-step explanation:

f(x) = 1/4(5-x)^2

f(x) = 1/4 (5-11) ^2

f(11) = 1.25 - 2.75 ^2

f(11) = 9

Area of triangle = 20 square yards

Step-by-step explanation:

The height of triangle = 5 yd

The base of triangle = 8 yd

We need to find area of triangle.

The formula used is: [tex]Area\: of\: triangle=\frac{1}{2}\times base \times height[/tex]

Putting values and finding area

[tex]Area\: of\: triangle=\frac{1}{2}\times base \times height\\Area\: of\: triangle=\frac{1}{2}\times 8 \times 5\\Area\: of\: triangle=4 \times 5\\Area\: of\: triangle=20\:square\:yards[/tex]

So, Area of triangle = 20 square yards

Answer:

Since slopes of both lines are not negative reciprocals. Therefore Lines are not perpendicular to each other

Step-by-step explanation:

Slope of -7x-2y=-8 is -7/2

Slope of 2x+7y=-3 is -2/7

For perpendicular lines slopes are negative reciprocals of each other

We can simplify it by multiply like terms,

⇒ (- 7 √3) × (11 √10)

⇒ (- 7 × 11) × (√3 × √10)

⇒ - 77 × √30

⇒ - 77√30

Therefore, The value of expression in simplified form is,

⇒ - 77√30

Answer:

254 ft

Step-by-step explanation:

first find the legs of the triangle.

you already know 65, and you would get another leg by 83-50, which equals 33.

Next use pythagorean theorem to find the other leg

a^2+b^2=c^2

rearrange so you find a leg

a^2=c^2-b^2

a^2=65^2-33^2

a^2=4225-1089

a^2=3136

a=56

Now you know that the missing leg is 56. Since that leg is the same as the short side of the rectangle, you 83+50+65+56=254
