Solve for the value of x :-5(x+4)+5(2-x)​

Mathematics
1 answer:
Mariulka [41]2 years ago
6 0

Answer:

30

Step-by-step explanation:

Given expression:

5(x + 4) + 5(2 - x)

Note: <em>The value of "x" is undefined because the given sum is not an equation. Thus, I will simplify the expression as much as possible. </em>

Let us simplify all the distributive properties stated in the expression.

Apply the distributive property rule <u>[a(b + c) = ab + ac]</u>

\implies5(x) + 5(4) + 5(2) - 5(x)

Since 5(x) is being subtracted from 5(x), we get:

\implies 5(x) + 5(4) + 5(2) - 5(x)

\implies 5(4) + 5(2)

Finally, let us simplify the sum of the product of (5 and 4) and (5 and 2).

\implies20 + 10

\implies \boxed{30}

The length of a rectangle is 7 centimeters greater than the width.
Lisa [10]

Answer:

length = 17cm, width = 10cm

Step-by-step explanation:

2L + 2w = 54

L = w + 7

Substitute:

2(w + 7) + 2w = 54

2w + 14 + 2w = 54

4w = 40

w = 10

L = 10 + 7 = 17

What’s the value of X In this????
kkurt [141]

Answer:

x = 68 degrees

Step-by-step explanation:

Step 1: We know this is a isosceles triangle

Since we know it is a isosceles triangle it has 2 of the same angle so the unknown side(not x) is 59

Step 2: Use the 2 angles to find 'x'

Angles in a triangle add up to 180 so we subtract 59 x 2 from 180 to get 68

Therefore angle x is 68 degrees
