Answer:

$A=\frac{1}{2}bh$

Step-by-step explanation:

In the formula listed above, "A" represents the area of the triangle, "b" represents the base of the triangle, and "h" is the height/altitude of the triangle.

This makes sense because the area of a square is base*height and a triangle is half of a square.

Solve this system of linear equations. separate x and y values with a comma. 7x=-67-11y 5x=-73-11y

Aleks [24]

Answer:

3, -8

(x is equal to 3 and y is equal to -8)

Step-by-step explanation:

The system:

{ 7x=-67-11y

{ 5x=-73-11y

Finding a value for x:

7x=-67-11y -> x = $-\frac{67}{7}$ - $\frac{11y}{7}$

Solving for y by plugging in our x:

[Equation] 5x = -73 -11y

[Plug-in] 5( $-\frac{67}{7}$ - $\frac{11y}{7}$ ) = -73 -11y

[Distribute the 5] $-\frac{335}{7}$ - $\frac{55y}{7}$ = -73 -11y

[Multiply by 7] 7 ( $-\frac{335}{7}$ - $\frac{55y}{7}$ ) = (-73 -11y) 7

[Simplify] -335 - 55y = -511 - 77y

[Add 335 and 77y to both sides] 22y = -176

[Divide by 22] y = -8

Plug in our y to solve for x:

5x = -73 -11y

5x = -73 -11(-8)

5x = -73 + 88

5x = 15

x = 3

What’s the surface area of a cylinder with a height of 6yd and width of 4yd

Marta_Voda [28]

Answer: 100.53096 (round if you need to)

Steps:
Surface area of cylinder formula = 2πrh + 2 πr^2

2πrh + 2 πr^2
2(π)(2)(6) + 2(π)(2^2)
2(π)(12) + 2(π)(4)
= 100.53096
