Answer:
1.78
Step-by-step explanation:
To solve for x we need to cross multiply it
We have = sign inbetween the fractions so we cross multiply it
9*x = 2* 8
9x = 16
Now we divide by 9 on both sides
so x= 1.7777777778
When we round to two decimal places then
x= 1.78
This is true because:
-57+27=-30
I think d because it's the longest side
Answer:
x=4 and x=3
Step-by-step explanation:
The first step to find all factors of 12
1,2,3,4,6,12
and their negative form
-1,-2,-3,-4,-6,-12
we must add two of these numbers to get -7
and the two numbers that add up to -7 are -3 and -4
we can simply plot them into the polynomial (x-3)(x-4)
since x-3=0
we add three to both sides to get x=3
and since x-4=0
add four to both sides
we get x=4
and now check out work which
we can use First out in last (foil) method
(x-3)(x-4)
first
x^2
out
-4x
in
-3x
last
12
now we simplify to get x^2-7x+12
so it x=4 x=3 works
Answer:
choice 1) <u>-7 + 4 = -3</u>
Step-by-step explanation:
Since -3--7 = 4, -3 = -7 + 4, -7 = -3-4
4 greater than -7 is 3.
