X^2+4x=-3
x^2+4x+3=0
(x+1)(x+3)=0
x+1=0 so x=-1
x+3=0 so x=-3
so the solution is x=-3,-1
Hope this helped! Please rate my answer if I helped you! Any questions please feel free to ask! Thank you so much!
108 because theres 18 in in one and your finding out how much in 6 so 18*6=108
Answer:
Length = 18 in
Width = 15 in
Step-by-step explanation:
We have that the area of a rectangle is:
A = L * W
but L = 1.2 * W
A = 1.2 * (W ^ 2)
1.2 * (W ^ 2) = 270
(W ^ 2) = 270 / 1.2
W ^ 2 = 225
Therefore, W is equal to:
W = 225 ^ (1/2)
W = +/- 15, but only +15 makes sense
W = 15
Now for L:
L = 1.2 * 15
L = 18
A = 15 * 18 = 270 in ^ 2
27/36 = n/4
27*4 = 36n
108 = 36n
108/36 = 36n/36
n = 3
Answer:
either 449/25 or 11/25 depends on the -14/5 or
Step-by-step explanation:
if it the first one then the answer should be 449/25 but if ut the second one it should be 11/25 .
u just substitute the -14/5 to x then solve
