Answer:

264 cm^2

Step-by-step explanation:

Area of a trapezoid = 1/2 (b1+b2) *h

The area of the large trapezoid

b1 = 14 b2 = 25 h = 10+12 = 22

A = 1/2 (14+25) *22 = 429 cm^2

The area of the unshaded trapezoid

b1 = 8 b2 = 25 h = 10

A = 1/2 (8+25) *10 = 165 cm^2

To find the area of the shaded region, take the area of the large trapezoid and subtract the unshaded trapezoid

429 - 165 =264 cm^2

The sum of two numbers is 90. Their difference is 18. Find the numbers.

Naddik [55]

Answer:

36 & 54

Step-by-step explanation:

By Question :-

Sum of numbers = 90 .
Difference of numbers = 18 .

Let :-

First Number be x .
Second number be y .

According to 1st condition :-

$: \implies$ x + y = 90

According to 2nd condition :-

$: \implies$ x - y = 18

Adding the equations :-

$: \implies$ 2x = 18 + 90

$: \implies$ 2x = 108

$: \implies$ x = 54

Therefore :-

$: \implies$ First number = 54

$: \implies$ Second number = 36

2(2x - 4) = 4(x - 2) What is the solution

galben [10]

Answer: 0

Step-by-step explanation:

2(2x-4)=4(x-2) - Start off by diong distributive property on both sides

4x-8=4x-8 - Add 8 to both sides toget rid of it

4x=4x - Divide both sides by 4

0 = 0 - The 2 equations are equal therefore the answer is 0

What is the value of t?

Lilit [14]

Hey!

-------------------------------------------------

I'm going to assume that the value of t is x.

-------------------------------------------------

Steps To Solve:

3(x - 2) = 6

~Distributive Property

→ 3x - 6 = 6

~Simplify

→ 3x + (-6) = 6

~Add 6 to both sides

→ 3x + (-6) + 6 = 6 + 6

~Simplify

→ 3x = 12

~Divide 3 to both sides

→ 3x/3 = 12/3

~Simplify

→ x = 4

-------------------------------------------------

Hence, x equals 4!

-------------------------------------------------

Hope This Helped! Good Luck!
