Vasily states that−6(5g−7h+9−10g)
1 answer:
Answer:
A. Vasily is not correct. He should have rewritten the original expression as −6(−5g−7h+9) and then as 30g+42h−54.
Step-by-step explanation:
Given the expression;
<em>Rearranging the above, we have;</em>
<em>Simplifying, we have;</em>
<em>Multiply, to open the bracket;</em>
<em>Therefore, Vasily should have rewritten the original expression as −6(−5g−7h+9) and then as 30g+42h−54. </em>

Answer:
x = 16
Step-by-step explanation:
SR = ST ⇒ Two sides are equal. So, ΔSRT is an isosceles triangle.
The angles opposite to equal sides are equal.
⇒ ∠STR = ∠R
∠STR = 4x - 28
Linear pair: If a ray stands on a line, then the adjacent angles are supplementary and they are called linear pair
∠STR + ∠STU = 180° {linear pair}
4x - 28 + 9x = 180
4x + 9x - 28 = 180 {Combine like terms}
13x- 28 = 180
Add 28 to both the sides
13x = 180 + 28
13x = 208
Divide both sides by 13
x = 208/13
