Let's evaluate ~

The given expression is :

$\qquad \sf \dashrightarrow \:4x + 8$

plug the value of x as 3

$\qquad \sf \dashrightarrow \:4(3) + 8$

$\qquad \sf \dashrightarrow \:12 + 8$

$\qquad \sf \dashrightarrow \:20$

Therefore, the required value is 20

Solve the right triangle. Will give points!

Anna [14]

Answer:

EF = 4.1
DE = 9.1
m∠F = 66°

Step-by-step explanation:

The hypotenuse and one acute angle are given. The relevant relations are ...

Sin = Opposite/Hypotenuse

Cos = Adjacent/Hypotenuse

For the given triangle, these tell us ...

sin(24°) = EF/DF = EF/10

EF = 10·sin(24°) ≈ 4.1

and ...

cos(24°) = DE/DF = DE/10

DE = 10·cos(24°) ≈ 9.1

The remaining acute angle is the complement of the given one:

F = 90° -D = 90° -24°

∠F = 66°

How many units long is a segment whose endpoints are (2,3) and (7,15)?

Ahat [919]

Answer:

13 units

Step-by-step explanation:

Distance formula: $d = \sqrt{(x2-x1)^2 + (y2-y1)^2}$

Simply plug in your variables

$d = \sqrt{(7-2)^2 + (15-3)^2}$

$d = \sqrt{5^2 + 12^2}$

$d = \sqrt{25 + 144}$

$d = \sqrt{169}$

d = 13

Answer:

a =74,321

b. 41,042,523,288

c. 414,832,917

Step-by-step explanation:

because two odd numbers becomes a even number

5 + 5 = 10 7 + 7 = 14 etc

so in the problem you sent 13 and 15 being odd numver will result in a even number when added
