Answer: 5
So the triangle KNL is an equilateral triangle meaning all angles are the same. If all angles are the same, all the lengths are the same.
If KL is 4, then NL is 4.
Since NL is 4, the opposite side LM is 4 because it is an isosceles triangle.
X - 1 = 4
X = 5
4/5*1/2= 4/10= 2/5, that is the answer of this equation
Answer:
a = - 2 and b = - 3
Step-by-step explanation:
Distribute the parenthesis on the left side then compare like terms on both sides.
4(3x - 6) - 7(2x + b)
= 12x - 24 - 14x - 7b
= - 2x - 24 - 7b
Compare to right side ax - 3
For the 2 sides to be equal then
- 2x = ax ⇒ a = - 2
and
- 24 - 7b = - 3 ( add 24 to both sides )
- 7b = 21 ( divide both sides by - 7 )
b = - 3

Answer:
Let's simplify step-by-step.
− x + 3 − ( x − 5 )
Distribute the Negative Sign:
= − x + 3 + − 1 ( x − 5 )
= − x + 3 + − 1x + ( − 1 ) ( − 5 )
= − x + 3 + − x + 5
Combine Like Terms:
= − x + 3 + − x + 5
= ( − x + − x ) + ( 3 + 5 )
= − 2x + 8
Answer:
= − 2x + 8

Original and bigger prism are similar with scale factor k = 4, so:
new surface area = k² * original surface area = 4² * 228 = 16 * 228 = 3648 m²
and
new volume = k³ * original volume = 4³ * 216 = 64 * 216 = 13824 m³
