I can help you with the first two problems. Since it's what I've recently studied.
19. Angles 3 and 4 (they are corresponding and alternative interior) are congruent with angle 6.
20. Angles 2 and 5 (corresponding and alternative interior) are congruent with 6.

3/8(2x-8/3x)=21 solve the equation for x

mart [117]

Answer:

$\boxed{\bold{x=-84}}$

Explanation:

Multiply Both Sides By 8:

= $\bold{8\cdot \frac{3}{8}\left(2x-\frac{8}{3}x\right)=21\cdot \:8}$

Simplify:

= $\bold{-2x=168}$

Divide Both Sides By -2:

= $\bold{\frac{-2x}{-2}=\frac{168}{-2}}$

Simplify:

= $\bold{x=-84}$

The perimeter of a rectangle is equal to 163 yard. The width is 8 more than twice the length. Find the length and width.

Sedaia [141]

Answer:

l = 29.4 yards

w = 66.8 yards

General Formulas and Concepts:

Order of Operations: BPEMDAS
Perimeter of a Rectangle: P = 2w + 2l

Step-by-step explanation:

Step 1: Define

P = 163 yards

w = 2l + 8

l = l

Step 2: Set up equation

P = 2w + 2l

163 = 2(2l + 8) + l

Step 3: Solve for l

Distribute 2: 163 = 4l + 16 + l
Combine like terms: 163 = 5l + 16
Subtract 16 on both sides: 147 = 5l
Divide both sides by 5: 147/5 = l
Rewrite: l = 147/5
Evaluate: l = 29.4 yards

Step 4: Find w

Define: w = 2l + 8
Substitute: w = 2(29.4) + 8
Multiply: w = 58.8 + 8
Add: w = 66.8 yards

If the volume of a cube is 729cm^3, what is the surfface area. Thanks!!

bezimeni [28]

Answer:

486cm^2

Step-by-step explanation:

cube volume: 729cm^3

cube faces count: 6

How you calculate square area:

s(cm) * s(cm) or just s^2(cm^2)

s = side length

If you want to find out the side length of a cube by its volume. Then simply just remove the ^3 by taking the cubic root (also written ^(1/3))

729^(1/3) = 9

then just calculate the area like i showed earlier:

(9cm)^2 = 81cm^2

But that is only one side of a cube's 6 sides, so multiply by 6:

81cm^2 * 6 = 486cm^2

Hope i could help :D
