A "straight angle" is a straight line.
The angle of a straight line is 180 degrees.
The value of 2 angles add together to make 180
One of the angles = 89 degrees
The value of the second angle = 180-89 = 91
Answer:
Choice C is the correct answer.
Step-by-step explanation:
Given expression is
(3p-7)(2p²-3p-4)
we have to find the product of linear expression to quardatic expression.
Firstly, multiply 3p to quardatic expression and -7 to quardatic expression and add.
3p(2p²-3p-4)-7(2p²-3p-4)
Multiply 3p to each term of quardatic expression and -7 to each term of quardatic expression and add all terms:
3p(2p²)+3p(-3p)+3p(-4)-7(2p²)-7(-3p)-7(-4)
6p³-9p²-12p-14p²+21p+28
add like terms
6p³+(-9-14)p²+p(-12+21)+28
6p³-23p²+9p+28 which is the correct answer.
Answer:
C. 2/9
Step-by-step explanation:
4/18=2/9
50 = 4*12.5
500 = 4*125
There are 125 -12 = 113 numbers between 50 and 500 that are divisible by 4.
Answer:
85 degrees
Step-by-step explanation:
So we can see that the two angles form a "c." This c indicates that it is a same side interior angle. Same side interioir angles are equal to 180 degrees. So, set both the expressions to 180.
x+90+x+100=180
2x+190=180
2x=-10
x=-5
Substitute in the value for x
-5+90=85
I hope this helps!
