Answer:
Area of the rectangle is 300, The perimeter is 70.
Step-by-step explanation:
Area = length x width
Area = 20 x 15
Area = 300
Perimeter = 2 x (length + width)
Perimeter = 2 x (20 + 15)
Perimeter = 2 x 35
Perimeter = 70

The following steps are used to rewrite the polynomial expression (x + 4y + z) (x - 7y). Step 1: x(x - 7y) + 4y(x - 7y) + z(x - 7y) Step 2: x2 - 7xy + 4yx - 28y? + zx - 7zy Step 3: x2 - 7xy + 4xy - 28y? + xz - 7yz Step 4: x2 - 3xy - 28y? + xz - 7yz Identify the property used in each of the steps:
The steps to simplify the expression is:
Step 1 :
x (x-7y) + 4y(x- 7y) + z (x- 4y)
Step 2:
x² - 7yx + 4yx - 28y² + zx - 4zy
Step 3:
x² -28y² - 3yx + zx - 4zy
What is Expression?A mathematical operation such as subtraction, addition, multiplication, or division is used to combine terms into an expression. In a mathematical expression, the following terms are used:
An absolute numerical number is referred to as a constant.Variable: A variable is a symbol that doesn't have a fixed value.Term: A term can be made up of a single constant, a single variable, or a mix of variables and constants multiplied or divided.Coefficient: In an expression, a coefficient is a number that is multiplied by a variable.We have the Expression:
(x + 4y + z) (x - 7y).
Step 1 :
x (x-7y) + 4y(x- 7y) + z (x- 4y)
Step 2:
x² - 7yx + 4yx - 28y² + zx - 4zy

A bank offers an annual simple interest rate of 8% on home improvement loans. Jake borrowed $17,000 over a period of 2 years. How much did he repay altogether?
A. $1,360
B. $2,720
C. $18,360
D. $19,720
Answer:
D
Step-by-step explanation:
Answer:
Step-by-step explanation:
We first find out the amount in dollars of interest accrued after 2 years time.
Interest = Prt
where P is the principal, r is the rate and t is time
8% written in decimal fraction → 8/100 → 0.08
Interest = 17000 × 8% × 2
Interest = 1700 × 0.08 × 2
Interest = 2,720 dollars
We add the principal and the interest to get full amount paid, so:
17000 + 2,720 = 19,720
Therefore the answer is D

The scale drawing of a field in the shape of a triangle is shown below. What is the actual area in square meters, of this field?
A.) 8.75
B.) 17.5
C.)35
D.)70
The actual area in square meters, of this field should be considered as the 70 m^2.
Calculation of the actual area:Since we know that
Area of the triangle = 1/2 * base * height.
here,
Base = 7, height = 5
And, Each square = 2 meters
So the area should be
= 1/2 * 14 * 10
= 70m
hence, The actual area in square meters, of this field should be considered as the 70 m^2.

angle----------- and------------ are supplementary to
FILL IN THE BLANK
Answer:
mRJN = 75°
Step-by-step explanation:
VJA = 15°
If the line VJ would continue through J and stop at a point that we now call Z. Then the new angle ZJN which is a vertically opposite angle to VJA would also be 15°
Angle VJE is supplementary to VJR and therefore also 90°
And if angle VJE is 90°, that means its supplementary angle EJZ is also 90°.
Angle EJN (supplementary to RJN) is simply EJZ - ZJN = 90° - 15° = 75°

You throw a number cube three times. What is
the probability that you roll an odd number all
three times? Write your answer as a decimal
A. 0.125
B. 0.5
C. 0.166
D. 0.25
Answer:
A. 0.125
Step-by-step explanation:
So since there is 6 numbers on a standered cube with 3 of those being odd numbers you have the fraction 3/6 but since you roll the cube three times you have 3/6 × 3/6 × 3/6. 3×3×3 is 27 and 6×6×6 is 216 you end up with 27/216. Lastly to make it a fraction you put 27 ÷ 216 in a calculator and get 0.125

c>−1.95
Step-by-step explanation:
Step 1: Simplify both sides of the inequality.
20>−3.2c+13.76
Step 2: Flip the equation.
−3.2c+13.76<20
Step 3: Subtract 13.76 from both sides.
−3.2c+13.76−13.76<20−13.76
−3.2c<6.24
Step 4: Divide both sides by -3.2.
−3.2c−3.2<6.24−3.2
c>−1.95
