What about it? 7x+5 equals what
Answer:
-30
Step-by-step explanation:
If you add -30 to both sides of the equation, you get 15 = m.
The expression after factorisation is 4w⁴x² (7y⁷ + 3w⁵x⁶)
<h3>What is an Expression ?</h3>
An expression is defined as a mathematical statement consisting of variables , constants and mathematical operators.
The expression given is
28w⁴x²y⁷+12w⁹x⁸
Factors of the given expression will be the common terms in both the terms
w⁴x² is common in the variable term
The HCF of 28 and 12 is 4
4w⁴x² (7y⁷ + 3w⁵x⁶)
The expression after factorisation is 4w⁴x² (7y⁷ + 3w⁵x⁶)

Step-by-step explanation:
a(n) = a +(n-1)d
d=1/4 -1/2 =-1/4
°.° a(15) = 1/2 +(15–1) -1/4
a(15) = 1/2 -3.5
=<u>-3</u>
