Answer:
(2x + 5)(2x + 1).
(6x - 5)(2x + 1).
Step-by-step explanation:
4x^2 + 12x + 5.
Use the 'ac' method:
a * c = 4 * 5 = 20 so we need 2 numbers whose product is 20 and whose sum is +12.:- 2 and 10 look good, so we write:
4x^2 + 2x + 10x + 5
Now we factor by grouping:-
= 2x(2x + 1) + 5(2x + 1)
= (2x + 5)(2x + 1) (answer).
12x^2 - 4x - 5
ac = 12*-5 = - 60 and we need 2 numbers sum to -4 . these numbers could be -10 and + 6:
12x^2 + 6x - 10x - 5
= 6x(2x + 1) - 5(2x + 1)
= (6x - 5)(2x + 1) (answer).
Answer:
C. JIL and KLI
Step-by-step explanation:
Well a interior angle is a curve type thing where two lines cross it will look like half a oval or circle. Your Using the letters to create this half and oval shape and to help us understand a Interior angle we know J,I, and L are connected so we can look at and connect those letting us know what the other one should look like. Connecting each option (KLN, JIG, KIL and HIG) Will let us know if they match JIL or not. KLN is smaller then JIL making it incorrect and that also tells us that JIG is incorrect since it matches KLN but compare it anyways. Now we check KLI doing that shows us that it does match JIL and it may be the answer but let's compare HIG to JIL anyways By doing this we see that HIG is a lot bigger and that it does not match JIL leaving us with choice C.
I hope this helped I had no idea what a Interior angel was so i looked up what it was then self taught from there im sure there is more to it, But I hoped this helped you have a great day!!! :)
Answer:
70
Step-by-step explanation:
If you use Pascal's Triangle, you will need 9 lines, since there are 9 terms in a binomial raised to the 8th power. Those 9 terms are:
1, 8, 28, 56, 70, 56, 28, 8, 1
The first expansion through the one we need are below (I hope you know how to use Pascal's Triangle!):
The third one down, I think!!!!
ANSWER: x = 4 ( 8 + 160 )
STEP BY STEP:
Let's start by getting a variable to represent the number. Let's use x. ⇩
x=
Now we know that there is a sum of 8 and 160. Let's add them to each other ⇩
x= 8 + 160
Now we know that this will be multiplied. Let's put parentheses around the addition to symbolize this.
X= (8 + 160)
Finally multiply this by four, making your equation
x= 4 (8 + 160)
I don't know the options but from looking at the problem I'm assuming the answer is
x = 4 ( 8 + 160 )
