Answer:
Side, Side, Side
Step-by-step explanation:
If 3 sides in one triangle are congruent to 3 sides in another triangle, then the triangles are congruent. This is called the Side-Side-Side (SSS) Postulate and it is a shortcut for proving that two triangles are congruent.

Hi.
102+6(7)+8 (your equation)
102+ 42+ 8 (since the order is PEMDAS, multiplication has to go first. 6x7=42
144 + 8 (since you go left to right, 102 +42 has to be 1st. Answer= 144)
152 (now the only thing left is 144 + 8, so do that. Answer= 152.)
Since that's the last step, 152 will be your answer.
Hoped I helped and if you need anymore you could always ask me~

Answer:
x = sqrt(11 - y) - 2 or x = -sqrt(11 - y) - 2
Step-by-step explanation:
Solve for x:
y = -x^2 - 4 x + 7
y = -x^2 - 4 x + 7 is equivalent to -x^2 - 4 x + 7 = y:
-x^2 - 4 x + 7 = y
Multiply both sides by -1:
x^2 + 4 x - 7 = -y
Add 7 to both sides:
x^2 + 4 x = 7 - y
Add 4 to both sides:
x^2 + 4 x + 4 = 11 - y
Write the left hand side as a square:
(x + 2)^2 = 11 - y
Take the square root of both sides:
x + 2 = sqrt(11 - y) or x + 2 = -sqrt(11 - y)
Subtract 2 from both sides:
x = sqrt(11 - y) - 2 or x + 2 = -sqrt(11 - y)
Subtract 2 from both sides:
Answer: x = sqrt(11 - y) - 2 or x = -sqrt(11 - y) - 2
Answer:
1
Step-by-step explanation:
what a tricky question.
pemdas- parenthesis, exponents, multiplication, division, addition, subtraction.
8/2(2+2)
add parenthesis first
8/2(4)
then multiply / distribute
2(4) is 8
finally
8/8 is 1
The sum of the interior angles in any given quadrilateral is always going to be 360.
This means each angle inside the quadrilateral added up with always equal 360 degrees.
