Answer:
f(g(x)) = 4x² - 12x + 9
Step-by-step explanation:
Substitute x = g(x) into f(x) , that is
f(g(x))
= f(2x - 3)
= (2x - 3)² ← expand using FOIL
= 4x² - 12x + 9

He uses 3/5kg of sugar to make a cake.
How much sugar does Patrick have left?
Answer:
7/30
Step-by-step explanation:
5/6-3/5 ,the LCM of denominators 6 and 5 is 30 ,6 denominator divided by 30 the result from the LCM times 5 the numerator is =25, 5 denominator divided by 30 the result from the LCM times 3 is =18 ,then subtract 25 from 18 giving you 7 ,then 7/6 or seven divided by six is one whole number, one over six

Three students were given the expression 2 - 7(3x – 4) to simplify
Use the drop-down menus to complete the statements about whether each student's
answer is an equivalent expression.
Then choose an expression that is equivalent
Answer:
Tessa's expression is false because -7 times -4 is positive 28, not -28.
Bernette's expressionis false because you must distribute the -7 before subtracting 7 from 2 (peMdas)
Lucy's expression is true because she correctly distributed the -7 to each of the terms in the parentheses and used PEMDAS.
2-21x+28
The equivalent expression for the given expression is 2-21x+28.
What is an equivalent expression?Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value for the variable.
Tessa:
2-7(3x-4)=2-21x-28
Tessa's equivalent expression is wrong. Because -7×(-4)=28 not -28.
Bernette:
2-7(3x-4)=-5(3x-4)
Bernette's equivalent expression is wrong. Because, you can not 2 and 7, since 7 is multiplied to the term 3x-4
Lucy:
2-7(3x-4)=2-21x+28
Lucy's equivalent expression is correct.
Therefore, the equivalent expression is 2-21x+28.

Find the measures of the indicated angles pictures included!!!
Answer:
25
Step-by-step explanation:
The angles b and 65 are complementary, meaning they sum to 90 degrees. You know this because those 2 angles and the right angle are sitting on a straight line. So, together they equal 180 and 180-90 is 90. Therefore, angle b+65 must equal 90. So, simply subtract 65 from 90 to get the answer, 25.

Find the least number which when divided by 28, 50 and 140 leaves a remainder 7
Answer: 21
Step-by-step explanation:
First we have to find LCM (lowest common multiple) of the given number, i.e 700.
28 = 2 × 2 × 750 = 2 × 5 × 5140 = 2 × 2 × 5 × 7LCM = 2 × 2 × 5 × 5 × 7 = 700
now, let's add 7 to 700
We get the required number as 707

looks like the answer C. Thousands.
In the number 72,204 the ones, tens, thousand, and ten thousand will be 4,0,2, and 7 respectively.
What are digits?In a positional numeral system, a numerical digit is a single sign that can be used singly or in combination to represent numbers.
A digit is a part of a set that, when combined, makes up a numeration system.
For example 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 are digits.
The place value of a general abcd digit is given by
d = ones
c = tens
b = hundreds
a = thousands
So,
In the given number 72,204
4 = ones
0 = tens
2 = hundreds
2 = thousands
7 = hundred thousand
Hence "In the number 72,204 the ones, tens, thousand, and ten thousand will be 4,0,2, and 7 respectively".
