Answer:
3x +45°=180° (due to straight angle)
or, 3x= 180°-45°
or,3x= 135°
or,X=135°/3
X =45°.ans
Answer:
4
Step-by-step explanation:
the Fundamental Theorem of Algebra states that for any polynomial of degree n, there are n roots, some of which may be complex
The polynomial shown is of degree 4 ( highest exponent of x )
Hence the polynomial has 4 roots/ zeros
Answer: x = -3
Step-by-step explanation:
3x - 9 = -18
1. Add 9 to each side.
3x-9=-18
+9 +9
3x=-9
2. Divide by 3.
3x/3 = -9/3
You are done.
x = -3
Ans: y = x + 4
workings in the pic below:) & I’m sorry if it’s wrong :(((!
A fact family needs to have at least 3 numbers. The first two numbers are added to give the third number. A fact family is used to show the Commutative Property of Addition. So,
3 + 4 = 4 + 3 = 7
The third number is 7
