-4
Step-by-step explanation:
(n + 5)2 for n = -7
= (-7 + 5)2
= (-2)2
= -4
Another way :
(n + 5)2
= 2n + 10
= 2(-7) + 10
= -14 + 10
= -4

Step-by-step explanation:
13)
5x becomes 5(2) which is 5 times 2 = 10
17)
(4x) + 7 becomes (4 times 2) + 7 = 15
21)
(2x) + (2y) becomes (2 times 2) + (2 times 3)
= 4 + 6
= 10
25)
1/2(z - x) becomes 1/2(4 - 2)
= 1/2(2)
= 1

Noah has a box of coins in his room. The box currently
contains 40 coins, consisting of pennies, dimes, and
quarters. The number of pennies is equal to the
number of dimes, and the total value of the coins is
$8.05. How many of each type of coin does Noah have
in the box?
The currency called the dollar can be divided or reduced into smaller forms also known as pennies, quarters, nickels and dimes.
The number of pennies is 5, the number of dimes is 5, the number of quarters is 30.
It is important to note that
a penny = $0.01
a dime = $0.10
a quarter = $0.25
Let's represent the number of
pennies = p
dimes = d
quarters = q
The number of pennies is equal to the number of dimes, hence:
p = q, so we can represent the number of pennies and dimes as y
The box currently contains 40 coins
So: 40 = y + y + q
q = 40 - 2y...........Equation 1
The total value of the coins is $8.05
So: 0.01y + 0.1y + 0.25q = 8.05 ........... Equation 2
We substitute 40 - 2y for q in Equation 2
0.01y + 0.1y + 0.25(40 - 2y) = 8.05
0.01y + 0.1y + 10 - 0.5y = 8.05
Collect like terms
0.01y + 0.1y - 0.5y = 8.05 - 10
-0.39y = -1.95
Divide both sides by -0.39
-0.39y/-0.39 = -1.95/0.39
y = 5
Since y represents the number of pennies and dimes, the number of pennies is 5 and the number of quarters is 5.
To solve for the number quarters, we would use equation 1
q = 40 - 2y...........Equation 1
q = 40 - 2 x 5
q = 40 - 10
q = 30
The number of quarters is 30.
Therefore, we have 5 pennies, 5 dimes, and 30 quarters.

A frog leaps off of a ledge and lands on the ground below. The function
f(x) = -1.6x2 + 2.3x + 3.2 represents the frog's path.
a. How high is the ledge where the frog starts?
b. How high is the frog at its highest point?
c. What is the frog's horizontal distance from the ledge when it
reaches its highest point?
Answer:
-1.6x2 + 2.3x + 3.2 = f(x) to solve this you do -1.6 x 2 = -3.2 + 2.3x = -0.9 + 3.2 = 2.3
Step-by-step explanation:
For A the height of ledge is 3.2
for b - the frogs highest point 2.30x
and c is 12.3x

Answer the question below
Find the value of x

Answer:
x = 8
Step-by-step explanation:
Supplementary angles add up to 180 degrees to make a straight line.
The red square in one of them indicates that it is 90 degrees on their side which means that it is 90 degrees on the other where (6x+2) and 40 degrees are.
(6x+2) + 40 = 90
6x + 42 = 90
6x = 48
x = 8
