Answer:
9 ft and 26 ft
we will take as x the width, then
P rect. = 2(A+B)
A = 2x + 8 | 2×x, because there is b twice less, and + 8, because there is at 8 longer
B = x
70 = 2(2x + 8 + x)
70-16 = 4x + 2x
54= 6 x
54/6 = 9 => B = 9; A = 2×9+8 = 26

1. -2- 3x + 2x + 5x + 4
Does Someone know how to do the work for this question?! Need ASAP
Answer:
5x^3-x+2
Step-by-step explanation:
We rearrange the formula grouping x together but preserving subtraction and start numbers from left.
- 2 -3x + 2x + 5x^3 +4
= -2+4
= 2
-3x +2x = -1x = -x
= 5x^3 +2 - x
= 5x^3 -x + 2
We cannot distribute unless we had the given values for x
if x = 1 and we were told this, then the equation would be set to zero +2 as you would be left with x^3 = 1 and x = 1 and 1-1 = 0
Then you would just need to apply +2 = 2.
But in standard form we leave the amounts 5x^3 -x +2
65% of what number is 39? 30% of what number is 15?
Please answer both questions.
Answer:
65% of what number is 39=25.35
30% of what number 15=4.5
Step-by-step explanation:
What is the value of x in the equation 3x-4y=65, when y=4?
O x=134
O x=21 1 / 3
O x=23
O x=27
Answer:
27
Step-by-step explanation:
3x-4y=65
3x-4(4)=65
3x-16=65
3x=65+16
3x=81
x=81/3
x=27
The base of a 15-foot ladder is 6 feet from a building. If the ladder reaches the flat roof, how tall is the building?
The height of the building is ft
(Simplify your answer. Type an exact answer, using radicals as needed.)
Answer:
the answer would be 13.75 feet
Step-by-step explanation:
The computation of the tall is the building as follows:
Given that
Base is 6 foot
And, the hypotheses is 15 feet
Here we use the Pythagoras theorem
= √15^2 - √6^2
= √225 - √36
= √189
= 13.75 feet
Hence the answer would be 13.75 feet

how long would the toy car be?...
Answer:
6.37 cm.
Step-by-step explanation:
Since Hot Wheels uses a scale ratio of 1:64 (1 cm to scale = 64 cm actual) for their toys, knowing that the actual length of a VW Beetle is 160.6 inches, to determine the length of the toy car is you must perform the following calculation:
1 inch = 2.54 cm
(160.6 x 2.54) / 64 = X
407.924 / 64 = X
6.373 = X
Therefore, the size of the toy car will be 6.37 cm long.
The medical practice you are working at has seen an average of 22.4 patients a day for the past 3 months. 3/4ths of those patients have insurance in one form or another. how to analyze and what the process you will use Please express to the nearest whole number how many of the patients on average per day do not have insurance, and thus, pay cash price for their visits.
Answer:
5.6 patients
Step-by-step explanation:
Given
[tex]Average = 22.4[/tex]
[tex]Insurance = \frac{3}{4}[/tex]
Required
How many do not have insurance (average)
First, calculatet he fraction of those without insurance (x).
[tex]x = 1 - Insurance[/tex]
Substitute value for Insurance
[tex]x = 1 - \frac{3}{4}[/tex]
[tex]x = \frac{1}{4}[/tex]
The number of visits is:
[tex]Visits =x * Average[/tex]
[tex]Visits = \frac{1}{4} * 22.4[/tex]
[tex]Visits = 5.6[/tex]

the one on the left is 3 times larger than the one on the right. in other words, the right triangle's dimensions times 1/3 is equal to the left triangle's dimensions.
find the slope of the line passing through the points (7,-6) and (-7,-6)
Answer:
1.1667
Step-by-step explanation:
Slope = change in y / change in x
Slope = (-6 - -6) / (-7 - 7)
Slope = 0/-14
Because the change in y is 0 the slope would be 0
Slope = 0

long division: Problem type 2 Divide, (12x3 +14x2+24x+9) = (4x2+2x) Your answer should give the quotient and the remainder Quotient: 3 3 Remainder: 1 X ?
9514 1404 393
Answer:
quotient: 3x +2remainder: 20x +9Step-by-step explanation:
Just as with numerical long division, the product of the partial quotient and the divisor is subtracted from the dividend to get the new dividend. The partial quotient is the ratio of the highest-degree terms of dividend and divisor. The process ends when the degree of the dividend is less than the degree of the divisor.
the size of a rectangular photo frame is 12 11/16cm by 8 3/4cm. Which of the following gives the product of these dimensions rounded to the nearest whole number of centimeters
answers
A) 12 cm x 8 cm
B) 12 cm x 9 cm
C) 13 cm x 8 cm
D) 13 cm x 9 cm
Answer:
D
Step-by-step explanation:
the answer can't be A or C because we know that 8 3/4 rounds to 9
so we have to figure out if 12 11/16 is closer to 12 or 13
anything above 8/16 should round up; therefore, 11/16 should round the 12 to be 13
Use synthetic substitution to find f(3) and f(-4) for f(x)= x^4 - 8x- 11.
Answer:
f(3)=56, f(-4)=277
Step-by-step explanation:
f(x)=x^4-8x-11
f(3)=3^4-8(3)-11=3*3*3*3-24-11=9*3*3-35=27*3-25=81-25=56
f(-4)=(-4)^4-8(-4)-11=(-4)(-4)(-4)(-4)+32-11=(16)(16)+32-11=256+32-11=288-11=277
