Answer:
(u + 1)(u - 1)(u² + 8)
Step-by-step explanation:
<u>Here is the steps:</u>
- u⁴ + 7u² - 8 =
- u⁴- u² + 8u²-8 =
- u²(u² - 1) + 8(u² -1) =
- (u² - 1) (u² +8) =
- (u + 1)(u - 1)(u² + 8)
Answer:
4
Step-by-step explanation:
if the required number is 'x', then the sum of 2 times the number and 10 is 2x+10; the difference of the number and 1 is x-1. Using these two equation it is possible to make up the common one:
2x+10=6(x-1);
4x=16;
x=4.
Paragraph Style Proof:
Angle A = Angle T is given to you. This is one pair of angles that will be used later on. Another pair of angles that are congruent is the pair angle AXM = angle TXH which are vertical angles. So far we have two pairs of angles that are congruent.
A pair of sides that are congruent is MA = HT which is the second piece of given information. Using the two pairs of angles, along with the pair of sides, we can use the AAS congruence theorem. The order is important. Notice how S is not between the two A's. So the sides are not between the two angles mentioned. If we were to use ASA, then we would need to know if AX = XT were true or not.
side note: SAA is the same as AAS. Again the S is not between the two A's.
