The solutions are:
x = −4,x = 7
Explanation:
X^2−3x−28= 0
We can first factorise this expression by splitting the middle term and then find the solutions:
= x^2−7x+4x−28=0
= x( x−7) + 4( x − 7)=0
=(x+4)(x−7)
Now, we can equate the two factors with zero and find the solutions:
x+4=0,x =−4x−7=0,x=7
To find the volume of a cube you multiply the length of any side by its self twice <span />
(-2, -1) so y = <span>-2(-2) + 3 = 7; FALSE
</span>(3, 3) so y = -2(3) + 3 = -3; FALSE<span>
(3, -3) </span>so y = -2(3) + 3 = -3; TRUE<span>
(-3, -9) </span>so y = -2(-3) + 3 = 9; FALSE
answer
<span>(3, -3)</span>
Answer:
2
Step-by-step explanation:
You can fit two groups of 3/8. 3/4 is equivalent to 6/8. 3/8 goes into 6/8 two times therefore the answer is two groups of 3/8.
