Given the equation:
To find the value of x, we will make a square for both sides as follows:
So, the answer will be x = 49
Answer:
Step-by-step explanation:
1) Sum = - 9
Product = -36
Factors = -12 , 3 {-12 + 3 = -9 & -12*3 = -36}
3a² - 9a - 12 = 3a² + 3a - 12a - 12
=3a(a + 1) - 12(a + 1)
= (a + 1) (3a - 12)
2) 4a² + 38a - 20 = 4a² + 40a - 2a - 20
=4a(a + 10) - 2(a + 10)
=(a + 10)(4a - 2)
3) 11a² + 30a - 9 = 11a² + 33a - 3a - 9
= 11a(a + 3) - 3(a + 3)
=(a + 3)(11a - 3)
Answer:
13
Step-by-step explanation:
if x = 5, substitute x for 5
3(5) - 2
now multiply
15 - 2
and subtract
13
U would add 5.3+7.2+6.2=18.6 then u'll do 9-1+1+-1=10
So ur answer would be 18.6y+10=
28.6
Well, one line is equal to 180
Starting with the bottom half, there is a right angle so 180-90 is 90
then take the degree that is given to you(47) and subtract it 90-47 is 43
so angle 4 is 43 <span>°
given that,andgle 3 is 90</span><span>° because its equal to the right triangle on the bottom
</span>2 is equal to 4(43<span>° )
</span>which leaves 1 to be 47<span>°
</span>
Hope this helps
