Area of the rectangle = L × W square units
A picture frame measures 16cm by 30cm on the outside, and 312cm^2 of the picture shows.
Let x be the increase in length and width. Then we have
(16 - x)(30 - x) = 312
x² - 46x + 480 = 312
x² - 46x + 168 = 0
x² - 42x - 4x + 168 = 0
(x - 42)(x - 4) = 0
x = 42, 4
The value of x can be more than 16. Then the value of x will be 4.
Then the width of the frame will be
W = 16 - x
W = 16 - 4
W = 12 cm

What is the solution for x2 + 4x < 77? –11 < x < 7 –7 < x < 11 x < –7 or x > 11 x < –11 or x > 7
Answers
Answer:
-11 < x < 7
Step-by-step explanation:
Inequalities:x² + 4x < 77
Subtract 77 from both sides
x² + 4x - 77 < 0
To find the zero points (Roots),
Make x² + 4x - 77 = 0
Now find the factors
x² + 11x - 7x - 77 = 0
x(x + 11) - 7(x + 11) = 0
(x +11) (x - 7) = 0
x + 11 = 0 or (x -7) = 0
x = -11 or x = 7
So, the solutions of the inequality is between (-11) and 7
-11 < x < 7
Answer:
x < –11 or x > 7 is the correct answer!!
Step-by-step explanation:
The answer above this was just slightly wrong. I took the exam and put my answer as option b and got it correct. Here is how I solved it correctly!
To solve the inequality x^2 + 4x > 77, we can factor the quadratic expression as (x - 7)(x + 11) > 0
To determine the solution, we consider the signs of each factor:
(x - 7) > 0 and (x + 11) > 0
This means x is greater than 7 or x is less than -11.
So, the simplified solution to the inequality x^2 + 4x > 77 is:
x < -11 or x > 7
If kinaata goes for swimming lessons every 5 days while Wayo goes every 6 days. if both kinaata and Wayo had swimming lessons together at the pool today, after how many days will both meet again at the pool for lessons?
Answers
Step-by-step explanation:
we need the least or smallest common multiple for both numbers, 5 and 6.
this is very simple for the small numbers here, but in general we look at the prime factors of both numbers :
6 has the prime factors 2 and 3.
5 has only 5.
so, the LCM is 2×3×5 = 30.
they will meet again after 30 days.
FYI -
the LCM is for larger numbers a and b not automatically a×b. if both numbers share prime factors, the LCM can be smaller than a×b, as the LCM is using every overlapping prime factor only once.

P(x) = x³ + 4x2 - 19x + 14

Answers
Answer:
x = - 7 , x = 2 , x = 1
Step-by-step explanation:
note that
p(1) = 1³ + 4(1)² - 19(1) + 14 = 1 + 4 - 19 + 14 = 0
since p(1) = 0 , then x = 1 is a zero
using synthetic division
1 | 1 4 - 19 14
↓ 1 5 - 14
------------------------
1 5 - 14 0
quotient is x² + 5x - 14
equating quotient to zero
x² + 5x - 14 = 0
(x + 7)(x - 2) = 0
equate each factor to zero and solve for x
x + 7 = 0 ⇒ x = - 7
x - 2 = 0 ⇒ x = 2
then zeros are x = - 7, x = 2 , x = 1

8. Write the equation of the line in slope-intercept form that has the following points: (4, 5) (-1,2)
Answers
Answer: y = 3/5x + 13/5
Step-by-step explanation:
To solve this you would have to use slope-point form Y − y1 = m(x − x1)
In this case, you would plugin your x and y values from your 1 point. It would look something like this. y - 2 = m(x + 1). But now the issue is we don't know our slope, To find out a slope you would use 2 - y1/x2 -x1 which would be 3/5 so, in the end, the equation would look like y - 2 = 3/5 (x + 1). Now solve for Y and your answer would be y = 3/5x + 13/5
