Answer:

Step-by-step explanation:

Corresponding parts of congruent triangles are equal.

VT = SR

8x- 17 = 15   {Add 17 to both sides}

8x = 15 + 17

8x = 32    {divide both sides by 8}

x = 32/8

x = 4

Corresponding parts of congruent triangles are equal.

∠V = ∠S = 60°

∠W = ∠U = 90°

∠T = ∠R = 2y + 20

In Δ VUT,

∠V + ∠U + ∠T = 180  {Angle sum property of triangle}

60 + 90 + 2y + 20 = 180

2y + 170 = 180

2y = 180- 170

2y = 10

y = 10/2

y = 5

(7x4 + 2x3 - 3) – (4x2 - 9x + 2)
abruzzese [7]

Answer:

7x4+2x3-4x2-5

Step-by-step explanation:

We will start solving this question by opening the bracket first

So let's solve

(7x4+2x3-3)-(4x2-9x+2)

7x4+2x3-3-4x2+9x-2

Collect like terms

7x4+2x3-4x2-3-2

7x4+2x3-4x2-5

So the final answer is 7x4+2x3-4x2-5

Ice on a lake gets thicker as long as the temperature is below freezing. On a certain lake it took 8 days for the ice to reach a
spayn [35]

The average rate of growth of the ice can be found by dividing the thickness by the number of days of growth

The growth rate of the ice over the 8 days is <u>0.375 inches/day</u>

Reason:

The known information on the ice are;

The time it took the ice to reach a thickness of 3 inches = 8 days

Required:

The (average) rate that the ice is growing in c=inches per day

Solution:

Rate \ of \ growth \ of \ ice= \dfrac{Increase \ in \ thickness}{ Time} = \dfrac{\Delta  \ Thickness}{\Delta T}

Therefore;

Rate \ of \ growth \ of \ ice= \dfrac{3 \ inches}{ 8 \ days} = 0.375 \ inches/day

The (average) rate of growth of the ice over the 8 days is <u>0.375 inches per day</u>
