You can’t? I mean like adding 100 at a time or-
Answer:
x^2+7x=30
x^2+7x-30=0
Here a=1,b=7 and c=-30
Now,
Discriminant(D)=b^2-4ac
=7^2-4×1×(-30)
=49+120=169
By applying Quadratic formula
x=-b+- root over b^2-4ac÷2a
=-7+- root over D ÷ 2×1
=-7 +- root over 169 ÷2
=-7 +- 13 ÷2
Now,
Either x=-7+13÷2=6÷2=3
Or x=-7 -13 ÷2=-20÷2=-10
Hence, ans is (C) x=-10 and x=3
Answer:
11.313708498984760390413509793678 (round that)
Step-by-step explanation:
use pythag thorem, a^2 + b^2= c^2
a is 8 and b is 8 so square both and add them 64+64= 128
then take square root of 128 to find length c
and you get 11.313708498984760390413509793678
you are welcom
Answer:
The factored form of the polynomial use the model to rewrite the expression is (X-7)(X-4)
Step-by-step explanation:
given the polynomial 
-11x+28
=> the value of all three parameters in the function are;
a: 1
b: -11
c: 28
=> the two number that has sum is = b= 11 and product is = c = 28 are: 4 and 7
Hence, the factored form of the polynomial use the model to rewrite the expression is (X-7)(X-4)
