Answer:
x= 5
the length = 13 meters
the width = 7 meters
Step-by-step explanation:
(2x+3)(x+2)=91
2x²+7x+6=91
2x²+7x-85=0
(2x+17)(x-5) =0
x=-17/2 or x = 5
the length = 2(5)+3= 13 meters
the width = 5+2 = 7 meters

when you plug in 1 to the denominator, 1 minus 1 becomes 0. a fraction with 0 as the denominator does not exist.
The limit of the function f(x)=[tex]x^{3}-1[/tex]/x-1 as x approaches 1 is 3.
What is limit?Limit is the value that a function approaches as the value of variable approaches some value. They are essential to calculas and mathematical analysis and are use to define continuity , derivatives and integrals. It can change value of function at different values of x.
How to find limit?We have been given a function f(x)=[tex]x^{3}-1[/tex]/x-1 and we have to find the limit of function.
F(x)=[tex]x^{3} -1[/tex] /(x-1) [[tex]x^{3} -y^{3} =x^{2} +y^{2} +xy[/tex]]
[tex]\lim_{x \to \0}x^{3}-1/x-1[/tex]
[tex]\lim_{x \to \0} (x-1)(x^{2} +1+x)[/tex]/x-1
[tex]\lim_{x \to \0} x^{2} +x+1[/tex]
change limit by putting x=1-h
[tex]\lim_{h \to \0} (1-h)^{2} +1+1-h[/tex]
Put the value of h=0.
=1+1+1
=3
Hence the limit of the function [tex]x^{3}-1/x-1[/tex] is 3.

Find the slope of a line parallel to a line with a slope of 4/5
Answers
Answer:
slope = 4/5
Step-by-step explanation:
The question is asking us to find the slope of the line that's parallel to the line whose slope is 4/5.
Recall that parallel lines have equal slopes.
So the slope of the line that's parallel to the one with a slope of 4/5 is 4/5 too.
Therefore, slope = 4/5.

A computer gererates 80 integers from 1 to 5 at random. The results are recrded in the table. What is the experimental probability of the computer generating a 2?
Answers
By cross multiplying, you get 5x=100.
Simplify and x is equal to 20 or 20%.
However, we still need to find how many 2s are in the 80 integers.
This can be found by multiplying the percent by the number 80.
So, 0.20(80)=16
Therefore the probability of getting 2 is 16/80 or 20%.
What is the slope of the line that passes through the points (5, 1) and (2, -7)?
Answers
Answer:
8/3
Step-by-step explanation:
We need to find the slope of the line that passes through points , (5,1) and (2,-7) . We can find the slope as ,
=> m = y₁ - y₂/ x ₁ - x ₂
=> m = -7 - 1 / 2 - 5
=> m = -8/-3
=> m = 8/3
Hence the slope of the line is 8/3 .What is the numerator called in a percent problem? What is the denominator called in a percent problem ?
PLEASE I NEED HELP NOW!!!
Answers
Answer:
A percentage or percent for short is a fraction; a fraction that always has the denominator as 100. Because the denominator of a percent is always a 100, no matter what the numerator is, we replace 100 with the percent symbol % after the number. By definition, for any number x, x% = x100.

Changes made to your input should not affect the solution:
Step by step solution :
STEP 1 :
Trying to factor by splitting the middle term
1.1 Factoring y2+14y+49
The first term is, y2 its coefficient is 1 .
The middle term is, +14y its coefficient is 14 .
The last term, "the constant", is +49
Step-1 : Multiply the coefficient of the first term by the constant 1 • 49 = 49
Step-2 : Find two factors of 49 whose sum equals the coefficient of the middle term, which is 14 .
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, 7 and 7
y2 + 7y + 7y + 49
Step-4 : Add up the first 2 terms, pulling out like factors :
y • (y+7)
Add up the last 2 terms, pulling out common factors :
7 • (y+7)
Step-5 : Add up the four terms of step 4 :
(y+7) • (y+7)
The solution is:
y = -7
The solution is:
y = -14 / 2 = -7

Required
Solving (a): O+ to A+
We have:
[tex]A+ = 45[/tex]
[tex]O+=90[/tex]
So, the ratio is:
[tex]O+:A+=90:45[/tex] ---- first comparison
Divide by 5
[tex]O+:A+=90/5:45/5[/tex]
[tex]O+:A+=18:9[/tex] ---- Second comparison
Divide by 45
[tex]O+:A+=90/45:45/45[/tex]
[tex]O+:A+=2:1[/tex] ---- Third comparison
Solving (b): AB- to AB+
We have:
[tex]AB+ =6[/tex]
[tex]AB-=4[/tex]
So, the ratio is:
[tex]AB-:AB+ = 6:4[/tex] ---- first comparison
Divide by 2
[tex]AB-:AB+ = 6/2:4/2[/tex]
[tex]AB-:AB+ = 3:2[/tex] ---- Second comparison
Multiply by 2
[tex]AB-:AB+ = 6*2:4*2[/tex]
[tex]AB-:AB+ = 12:8[/tex] ---- Third comparison
Solving (c): B+ to total
We have:
[tex]B+ = 20[/tex]
[tex]Total = 195[/tex]
So, the ratio is:
[tex]B+ : Total = 20 : 195[/tex] ---- first comparison
Divide by 5
[tex]B+ : Total = 20/5 : 195/5[/tex]
[tex]B+ : Total = 4 : 39[/tex] ---- Second comparison
Multiply by 2
[tex]B+ : Total = 20*2 : 195*2[/tex]
[tex]B+ : Total = 40 : 390[/tex] ---- Third comparison

USING SIMILAR TRIANGLES IN INDIRECT MEASUREMENT If the shadow of a tree is 14 m long and the shadow of a person who is 1.8 m tall is 4 m long, how tall is the tree? Which of the following proportions could not be used to solve the problem? 14/1.8 = x/4 x/1.8 = 14/4 x/14 = 1.8/4
Answers
Answer:
14/1.8 = x/4
Step-by-step explanation:
Using similar triangles,
height of man/length of man's shadow = height of tree/length of tree's shadow
1.8/4 = x/14
x/14 = 1.8/4
If we cross-multiply, we have
1.8 × 14 = x × 4
dividing both sides by 4 and 1.8,we have
14/4 = x/1.8
x/1.8 = 14/4
So, the two expressions we have are
x/14 = 1.8/4 and x/1.8 = 14/4.
So, the answer is 14/1.8 = x/4 since the product 1.8 × 14 = x × 4 cannot be expressed in the given ratio.
