Please help. Find the two missing sides and write your answer as in simplified radical form.

ki77a [65]

Answer:

x and y = 5√2.

Step-by-step explanation:

This is a 45:45:90 triangle so length of x = length of y.

In this triangle the ratio of the sides is 1:1:√2

Finding length of x and y:

1/√2 = x/10

√2x = 10

x = 10/√2

= 10√2/2

= 5√2.

Solve 4(x + 2) = 20

KiRa [710]

Answer:

x = 3

Explanation:

$\sf 4(x + 2) = 20$

$\sf 4x + 8 = 20$

$\sf 4x = 20 - 8$

$\sf 4x = 12$

$\sf x = \frac{12}{4}$

$\sf x = 3$

check:

4(x + 2) = 20

4(3 + 2) = 20

4(5) = 20

20 = 20

Hence proved x = 3

Solve for c.<br><br> 2(c +1) = 10

coldgirl [10]

Answer:

c=4

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

2(c+1)=10

(2)(c)+(2)(1)=10(Distribute)

2c+2=10

Step 2: Subtract 2 from both sides.

2c+2−2=10−2

2c=8

Step 3: Divide both sides by 2.

2 = 8

c=4
