Can some one help me plz with step by step x^2 + x - 42

Mathematics
1 answer:
Alexeev081 [22]3 years ago
3 0

Answer:

x = 6 or x = -7

Step-by-step explanation:

Solve for x over the real numbers:

x^2 + x - 42 = 0

The left hand side factors into a product with two terms:

(x - 6) (x + 7) = 0

Split into two equations:

x - 6 = 0 or x + 7 = 0

Add 6 to both sides:

x = 6 or x + 7 = 0

Subtract 7 from both sides:

Answer: x = 6 or x = -7

Answer: 2nd one

Step-by-step explanation: Look at the options. In all of the options, the number of 0's is 3 so you don't have to look for the zero's. Next look at the one's. The first 2 have 2 ones and the next 2 have 3. The number of ones in the data is 2 so you can eliminate the last 2. Then look at the 2's between the top 2. In the first one, there is 2 and in the second one there is only one. In the data table, there is one 2 so the answer has to be the 2nd one. Hope this helps :)

(Multiying by a unit fraction. Find the product mentally. (5.6) × 1/8=
Ipatiy [6.2K]

Step-by-step explanation:

(5.6) × 1/8

(5.6)  \cdot   \frac{1}{8}

Here the unit fraction is 1/8

multiply 5.6 times 1

so its 5.6. then divide the decimal by 8

we know that 8 times 7 is 56

so 56 divide by 8 is 7

we have decimal point 1 number to the left

so we move decimal point 2 place left

Hence 5.6 divide by 8 is 0.7

(5.6)  \cdot   \frac{1}{8}=0.7

Answer: 0.7

Help I will be marking brainliest!!!
expeople1 [14]

Answer:

A. 51°

Step-by-step explanation:

By the theorem of intersecting secants.

m\angle B=\frac{1}{2} (m\widehat{LW} - m\widehat{MU})

44.5\degree =\frac{1}{2} (140\degree - m\widehat{MU})

2\times 44.5\degree = 140\degree - m\widehat{MU}

89\degree = 140\degree - m\widehat{MU}

m\widehat{MU} = 140\degree -89\degree

m\widehat{MU} = 51\degree
